Operator advises users to delay from installing the update because of problems with calls, texts and browsing the internet
Vodafone has warned people using the Apple iPhone 4S not to upgrade to iOS 6.1 because of reported 3G problems.
The operator said the upgrade to the latest version of Apple’s operating system affects 3G performance, with some customers having difficulty making or receiving calls or texts, as well as connecting to the internet.
Users have also written posts on Apple’s support forums complaining of a rapid reduction in battery life when upgrading to iOS 6.1, but others have said that restoring the smartphone using iTunes solves the problem.
A Vodafone spokesperson said: “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 the problem has been fixed.”
The operator also sent a text message to users of the smartphone over the weekend that read: “If you’ve not already downloaded iOS 6.1 for your iPhone 4s, please hold off for the next version while Apple fixes 3G performance issues. Thanks.”
Apple is yet to comment on the reported 3G problems or battery life issues.
The manufacturer made iOS 6.1 available on January 28. It has started sending out the next update, iOS 6.1.1, to developers.
