Vodafone UK has called on iPhone 4S users to hold back on upgrading to iOS 6.1 which it says impacts performance over 3G networks.
The operator said at the weekend that customers may be occasionally experiencing difficulty connecting to the 3G network to make or receive calls or texts or to connect to the internet.
“Apple is working on a solution to their software issue,” the operator said in a statement on its tech forum.
“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,” Vodafone said.
