UK carrier, Vodafone is warning its iPhone 4S users against upgrading to iOS 6.1. According to Pocket-Lint the network provider confirmed that it has concerns over 3G performance, and is advising customers to hold off until Apple addresses the issue with a fix.
We don’t know the extent of the issue. But, if you’ve experienced some less than pleasing 3G performance since updating to 6.1, let us know. It is rather interesting that we hear of Voda’s issues with 3G on iPhone 4S the same day we read that its CEO stated that 4G was for “technofreaks”.
