Vodafone certifies iOS 6.1.1 safe for use with iPhone 4S
Apple finally issues fix for bug that left some users unable to text or call.


Vodafone customers have been given the all clear to upgrade their iPhones to the latest version of iOS following the discovery of a bug that caused connection problems.
Version 6.1 of iOS was unveiled two weeks ago by Apple, but iPhone 4S users were warned by Vodafone UK not to install the update because it left some phones unable to make and receive calls, send texts or browse the internet.
The mobile operator warned users not to upgrade to iOS 6.1 until a bug fix was announced, which Apple has now released called iOS 6.1.1.
Vodafone has certified the update as safe to install.
In a forum post, a spokesman for Vodafone, said: "Apple has released a new version of its iPhone software that fixes the 3G performance issues that have been affecting users of the iPhone 4S who had installed iOS 6.1.
"Please download the latest version iOS 6.1.1 from Apple as soon as you can as this will deal with these issues," he added.
The updated version of iOS 6 promised enhanced support for LTE networks on the iPhone 5 and faster internet browsing.

However, some users complained of connection problems and poor battery life after the update had been installed.
Meanwhile, other problems have also surfaced with iOS 6.1. According to a report on Microsoft Technet, users running the updated OS claim their devices now constantly ping Exchange servers, forcing administrators to ban them until the problem was fixed.
It is unclear whether owners of non-iPhone 4S devices will get iOS 6.1.1. Apple has also yet to make any official comments on what caused the problem in the first place.
