Hold the phone!
UK cell phone provider Vodafone has warned customers using iPhones to not upgrade to iOS 6.1 due to apparent issues with 3G functionality. MacRumors reports that Vodafone sent SMS messages to all iPhone users on its network asking them to hold off on updating to iOS 6.1 for the time being.
"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," the message read.
Vodafone further explained its request via the support forums on its website. The carrier said it's aware of an issue with Apple iPhone 4S handsets that have been upgraded to iOS 6.1. The issue affected 3G performance and some users are experiencing difficulty connecting to the network or receiving calls and texts.
According to Vodafone, Apple is working on a fix. In the mean time, the carrier wants anyone who hasn't yet upgraded to delay doing so until Apple can confirm the issue has been resolved.
No word of advice for those that have upgraded and are experiencing issues, but we'll keep you posted on any developments.
