Faster 3G on Next iPhone
Apple's next iPhone should have improved Internet access, SAI claims. A "plugged-in" tipster in the cellular business has told the publication that a "significantly faster" connection will be part of the update without mentioning other details. It's not known whether the unnamed insider is alluding to the cellular access or to Wi-Fi, either of which is potentially upgradeable with the update.
However, the most likely change is the addition of support for speed-doubled 7.2Mbps 3G given both hardware manufacturer and carrier plans. Infineon should have a new 3G chipset starting from mid-year that would support the faster speeds while also improving battery life. At the same time, AT&T has been trialing 7.2Mbps 3G since late 2008 and should roll out the speedier service this year. The provider has stressed that many of its cell towers can be upgraded solely through software rather than new equipment.
Current iPhones are limited in hardware to 3.6Mbps 3G and couldn't themselves be upgraded.
If Wi-Fi is improved, a potential candidate is a new Broadcom 802.11 chipset that would provide real Wi-Fi speeds of up to 50Mbps (versus 25Mbps for typical 802.11g) in addition to Bluetooth with support for wireless stereo audio.
