UK network Vodafone is warning users of iPhone 4S handsets on its network to avoid upgrading to iOS 6.1. Vodafone is sending out text messages to its users as well as issuing a statement that claims Apple is already working on a fix for the problem. Apparently it is only affecting iPhone 4S users and is an intermittent 3G problem causing failed calls and texts as well as internet access problems.
We’re aware of an issue caused by Apple iPhone 4s handsets that have been upgraded to iOS 6.1 which impacts performance on 3G.
Some customers may occasionally experience difficulty in connecting to the network to make or receive calls or texts or to connect to the Internet. Apple is working on a solution to their software issue. These connection problems are intermittent.
While Apple’s investigations continue, we would recommend that anyone who has not yet installed iOS 6.1 on their iPhone 4s should delay doing so until Apple has confirmed that their problem has been fixed.
We know that Apple has already released iOS 6.1.1 beta to developers for testing and maybe this contains the fix that Vodafone is referring to. As with any new release of iOS firmware there are always many differing reports especially when it comes to battery performance. This release has been no different in that respect however the fact that Vodafone felt the need to publicly comment on this particular 3G problem does mean it could well be a major problem for many on its network.
My wife actually has an iPhone 4S on the Vodafone network in the UK and it is updated to iOS 6.1. Her iPhone is working perfectly with no sign of any issues with 3G. If there are any other readers on Vodafone in the UK experiencing any issues, please let us know in the comments!
