The next iPhone dubbed iPhone iPhone 5 or 10s? Tech-Blogs to read, depending on the application, it may be either. But the report of the Fortune proposes that both devices on the way.
Deutsche Bank, according to Chris Whitmore of Apple's Smartphone is running in the company of a lot of fans hyped iOS 5 (on iPhone (5), of course) on their handset, and a lower-cost level in pick, the optimized version of the iPhone 4 (dubbed iPhone-4S respectively, to follow up on the iPhone 3 G, iPhone 3GS). Whitmore also said the lock on the iPhone-4S version of the $ 349, and Pre-paid along 4,47 He noted that the provision of appeal to the growing proportion of the average handset range of Smartphone devices in the market, Apple has yet to really penetrate into the region.
Whitmore was not the only one to contribute to the development of hype over the the next iPhone (s); Morgan Stanley analyst Katy Huberty, announced Sunday, please note that Apple will begin the next iPhone and industry clients "in the mid-late August, and the ramp to aggressively" (as reported by Appleinsider). In addition, he said that the message of the device to hit the shops near the end of Q3, which ends in September. This points to iPhone-4S and/or the iPhone? 5 We have to wait and see, but Apple's next Smartphone to get closer and closer, are, on the horizon.

Higher power
There is accumulating evidence that cellphones that operate on GSM networks emit significantly more radiation than do cellphones operating on CDMA networks. This is not apparent when you look at a phone’s specs, Moskowitz said, because phone companies are required to list only the “specific absorption rate” (SAR) — the measure of the rate at which energy from a radio frequency electromagnetic field is absorbed by the body — of a phone at its maximum radiation output. “The SAR can be misleading as it measures the maximum radiation a cellphone emits and does not reflect the average amount of radiation it emits,” Moskowitz told Life’s Little Mysteries.
Several recent studies have shown that CDMA phones normally emit a small fraction of their maximum radiation output, while GSM phones emit, on average, half the maximum, he explained. This comes down to the different radio frequency (RF) bands that the two networks operate on, and the different methods by which the two networks carry phone transmissions.
“When a GSM phone transmits, it immediately goes to the peak power, and then the power control circuitry ratchets down the power to an acceptable level,” explained Mark McNeeley, an electrical engineer at Exponent Engineering and Scientific Consulting services and co-author of a recent study comparing GSM and CDMA networks. “CDMA networks share the same frequency among many different phone calls, so all phones transmit at the lowest possible power level necessary to maintain the fidelity of the call.” It’s like people talking quietly at a party, he said.
The radiation spikes at the beginning of GSM phone calls means that they emit, overall, up to 28 times more radiation than CDMA phones, according to a study co-authored by McNeeley and published last year in the Journal of Exposure Science and Environmental Epidemiology.
There are exceptions. If you have a CDMA phone in a rural area and the nearest CDMA cellphone tower is far away, then you have to broadcast at a radiation level that is equal to or greater than GSM to reach the tower, McNeeley said. If there is a GSM tower much nearer to you, you might be better off going with a GSM network, he said; but in most parts of the country, where both CDMA and GSM towers are ubiquitous, CDMA phones will emit less radiation than GSM phones.
What does radiation do to the brain?
Although dozens of international studies have been conducted over the past decade, some of which point to higher incidences of certain types of brain cancers in people who use cellphones heavily, the negative side effects of cellphone usage remain undetermined.
A possible consequence of the higher radiation output of GSM phones was seen in a study published in the International Journal of Science Technology & Management in April. Researchers compared brain scans of people talking on GSM phones and CDMA phones and found that the former stimulated much more brain activity than the latter.
Although it’s still unclear what that extra brain activity is, how it’s caused or whether it’s bad, other studies have also shown varying health consequences of using GSM versus CDMA phones. Of 37 studies that have examined GSM phones, 43 percent have found harmful biological effects from the phones — such as a decrease in the expression of genes that help suppress tumors — Moskowitz said, while only 15 percent of the 33 studies that looked at CDMA phones have identified harmful effects.
When reached for comment on the possible hazards of GSM phones, AT&T referred to previous statements by the Federal Communications Commission and the Food and Drug Administration that said the available scientific evidence shows no proven health risk of radiofrequency (RF) energy. The FDA states: “Although evidence shows little or no risk of brain tumors for most long-term users of cellphones … people who want to reduce their RF exposure can: reduce the amount of time spent on the cellphone, and use speaker mode or a headset to place more distance between the head and the cellphone.” T-Mobile did not return telephone calls or emails.
What to do?
GSM and CDMA networks work so differently that a phone built for one cannot operate on the other. Furthermore, AT&T and T-Mobile cellular networks, which are GSM, cannot simply switch and become CDMA networks. Given these facts, if you own a GSM phone, should you switch to a carrier that supports CDMA? Experts have mixed opinions.
It is difficult to say whether higher radiation output is bad, simply because the jury is still out on whether cellphone radiation is bad in the first place, says Ken Foster, a professor of bioengineering at the University of Pennsylvania who has been studying the effects of radiofrequencies for 40 years. The radiation level of cellphones — all cellphones — is so low it is considered “non-ionizing.” It isn’t powerful enough to knock electrons off atoms in cells and potentially change the structure of DNA molecules, which is the way that ionizing radiation (like gamma-rays and X-rays) causes harmful mutations. No one knows by what mechanism non-ionizing radiation, such as RF from cellphones, could possibly damage DNA, Foster says.
Though Foster grants that consumers could probably reduce their exposure by choosing CDMA rather than GSM phones, he doesn’t think it’s likely a higher radiation output actually makes GSM phones more hazardous than CDMA phones. The radiation levels of both phone types are so low, he said, that there is no known way they could harm DNA.
“If you take a shower at 160 degrees Fahrenheit, that could burn you. But I personally don’t fear a shower at 65 degrees Fahrenheit more than one at 63 degrees — neither temperature is dangerous,” he said. In his view, cellphone radiation on either type of network is as harmless as two cold showers of slightly different temperatures.
If cellphones are a biohazard, Foster said, that can’t be related to the amount of the radiation they emit. “Presumably, some parameter other than [radiation output] would be involved.” No one has identified what aspect of cellphone radiation is dangerous, Foster said, so there is no way of knowing whether GSM phones are worse for you than CDMA phones, or vice versa.

Hazardous frequencies
However, according to other scientists, there is some evidence that the potentially hazardous aspect of cellphone radiation may be the way in which transmissions are modulated — the way individual pulses of radiation are constructed out of a range of frequencies. The modulation pattern is different for CDMA and GSM phones, and some scientists think GSM pulse modulations may have adverse biological effects.
A review article in the April issue of the journal BioElectroMagnetics by Jukka Juutilainen and colleagues at the University of Eastern Finland suggested that specific types of RF modulation may well have biological consequences.
“While the majority of recent studies have reported no modulation-specific effects, there are a few interesting exceptions indicating that there may be specific effects from amplitude-modulated RF fields on the human central nervous system. These findings warrant follow-up studies,” the researchers wrote.
According to Moskowitz, the study found that GSM phones contain radiation at a frequency of 8 hertz, or 8 cycles per second, which “is in the range of ‘possibly carcinogenic’ because our cells have processes on that frequency level, with which the phone radiation may be interfering,” he said.
Foster, on the other hand, thinks there is no robust evidence that one type of modulation is more dangerous than the other. “To my knowledge, nothing shows a clear effect of pulse modulation,” he said.
Wanted: more evidence
Do some mobile phone networks pose more of a health risk than others? Though some researchers suspect so, it is too soon to say for sure. “Clearly more comparative studies are needed,” Moskowitz said.
At this point, all cellphone users should be cautious. “My first recommendation is to keep a safe distance from your phone. Text instead of calling. Use the speakerphone. Use a headset,” Moskowitz said. Radiation levels fall off rapidly with distance — so rapidly that you can decrease your brain’s exposure to a negligible level simply by keeping your phone antenna just a few inches away.
Moskowitz also thinks people should avoid keeping their cellphones on in their pockets. “There’s accumulating evidence of a risk to sperm and male fertility,” Moskowitz said. “People are forgetting where they’re keeping their cellphones all day long.”
Foster doesn’t believe cellphone radiation poses a significant danger, but he still suggests that people take precautions if they’re worried, just for peace of mind. “My best advice to consumers: If they are concerned about possible radiation risks from cellphones, use a hands-free kit, which actually does reduce exposure and costs very little.”

Google has issued an official response to the Federal Trade Commission investigation, search of the giant in the business. VentureBeat, reported by and posted on the Google official blog, the answer it is stated that the company's work with the FTC and the Agency's questions.
Post, author, and Google Fellow Amit Singhal has worked, "says, we strive to offer relevant answers as quickly as possible — and to us the product innovation and design talent has been delivered to the results that users seem to like the world where the competition is just one click. Still, we recognize our success has led to greater scrutiny. "
Singhal has worked in the State, goes to that, Google has not yet been "unclear exactly what the FTC's concerns are, but we are clear about where you support."
The New York Times says the FTC investigation: n could be, "delete, for the most serious showdown, and shall be taken of the Unied u.s. Government technology company in the Microsoft antitrust trial, which began in late 1990, after 's.".
The times also quotes FairSearch.org, the representative of the critics, including Microsoft and travel websites Expedia and Travelocity, which States, "the anti-competitive practices also scraping and using the content of other companies without authorization, the deceptive display search results, search results, to facilitate the manipulation of Google's products, and competitive threats to Google's dominance of the acquisition by Google, a certificate issued by the group."Google's policies are deserving full-scale investigations in the United States, the antitrust authorities. "
But in a post on his blog, Singhal has worked for Google, says that there is a check that users. "Available for retrieving information about a lot other alternatives: other general interest in search engines, specialized search engines, direct transition to the Web sites, applications, social networks, and much more. Because of the many options available, We do the search, the better to deal with the ongoing and will continue to monitor the principles which have guided us from the beginning. "
