iPhone 4S Lacks Enable 3G Switch in Network Settings
This is just odd. Appleís iPhone 4S lacks the ďEnable 3GĒ switch found in Appleís other versions of the iPhone.
The switch, found in the Network Settings Menu, allows users to switch of 3G data on their device, prolonging their battery life, especially in areas where 3G is absent. A reader tipped Engadget
off with a photo of their 4S on Vodafoneís network, showing the witch was absent. Engadget
checked their 4S running on AT&Tís network here in the U.S. and confirmed that it too lacked the enable 3G switch.
While this isnít a make or break issue, it does seem odd that Apple would prevent users looking to optimize their battery life from doing so. Apple hasnít officially responded to questions regarding the reason for dropping the switch on 4S devices. Appleís other phones (3GS, iPhone 4) that are upgraded to iOS 5 still have the option available in their Network Settings, so this isnít an iOS 5 specific issue.
AT&T users specifically might have an issue not being able to turn of 3G services on their phone. AT&Tís 3G coverage is poor bordering on horrible in many areas. Unless the 4S is somehow optimized to no search for 3G towers constantly, many owners in rural, or poor 3G service areas could see a considerable drop in battery life.
This image was sent in by MMi member Andrew Evans and shows that his CDMA iPhone 4 lacks the 3G Enable Switch as well. Perhaps the reason the iPhone 4S lacks the ability to switch between 3G and 2G networks has to do with the new baseband chipset that includes both CDMA and GSM radios. This would explain why GSM iPhone 4, and iPhones retain the 3G switch, but the CDMA versions do not.
