Fixes signal issues suffered after the recent 6.1 update.
With the new release of iOS 6.1 you would have assumed that Apple would have done their homework before releasing such a big patch out to all their devices. Turned out the iPhone 4S didn’t sit well with the new update as news started streaming in that people were having dropped connections, or worse yet, no connections at all. The issue plagued both regular reception and 3G connectivity.
Yesterday, however, Apple released a small patch as told by MacRumors, dubbed iOS 6.1.1 designed specifically for the iPhone 4S which literally “fixes…cellular performance and reliability for iPhone 4S”. So all you iPhone 4S owners should get this update ASAP, the rest of the iOS device owners needn’t bother.
