Last year, pre-orders for the Apple iPhone 4 outnumbered the reservations for the iPhone 3GS by a factor of 10 which taxed AT&T's servers, slowing down communications. Some complained of problems yesterday getting through to AT&T to reserve an Apple iPhone 4S. The device will be launched on October 14th in U.S., Australia, Canada, France, Germany, Japan, and the U.K. Changes made to the current model include the addition of a dual-core A5 processor (replacing a single-core A4 processor), an 8MP camera (up from 5MP) an improved antenna system and the Siri voice recognition technology.
There is some question about whether or not the Apple iPhone 4S can actually run at HSPA+ speeds. Speculation is that Apple and AT&T are working together to get the network indicator on the AT&T variant of the Apple iPhone 4S to read 4G when the phone is running over the mobile operator's HSPA+ network. While the guys at Cupertino have added the ability for the iPhone 4S to run at 14.4Mbps, a document released by AT&T last month notes that the carrier's HSDPA devices generally run between 3.6 and 7.2Mbps, though most AT&T users experience lower rates than that.
According to TiPB, the Apple iPhone 4S is said to be an HSPA+ phone only because of a technicality. While many feel that a phone should have speeds of 21Mbps to qualify as an HSPA+ device, and therefore be called 4G, the Apple iPhone 4S runs at a maximum of 14.4Mbps. But since the phone can run any 3GPP Release 7 feature, it is still considered an HSPA+ device and thus, a 4G phone. The ITU says that HSPA+ can be considered 4G because certain carriers in the U.S. were advertising it as such.
