Vodafone: Don't upgrade your iPhone 4S to iOS 6.1
Via their online support forum, Vodafone have warned customers with iPhone 4S models not to update to iOS version 6.1. Apparently iOS 6.1 is causing issues with 3G and can also impact the device connecting to the network.
I've a number of colleagues that started to report issues with the iPhone's shortly after the update and, guess what, we too use the Vodafone network.
Furthermore, they are all reporting that the battery life following the update has been dramatically shortened, but this could be part of the issues with the phone struggling to connect to the network.
The statement from Vodafone can be seen below:
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.
