The updated version of the iOS 6.1, which was labeled with the build number of 10B145 and is a 23-MB download, is expected to address the issues brought by iOS 6.1 that reportedly affected the cellular performance and reliability of iPhone 4s devices.
Last week, Vodafone issued a warning to their customers in the United Kingdom, saying that they should avoid upgrading their devices because there were reported issues caused by iOS 6.1, particularly the 3G-performance drop of the iPhone 4s.
The company posted: “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 their problem has been fixed.”
Aside from the phone’s 3G performance, those who updated their device to iOS 6.1 experienced a significant drop of their device’s battery life, while some corporate companies kept iOS 6.1 users out of their calendar functions because of an unspecified bug.
A test performed by Gotta Be Mobile on their iPhone 4s showed that the battery life dropped to 2 hours and 45 on standby – 45 percent lower than the battery life before the update. A test performed using an iPhone 5 also showed 10-15 percent drop. And because it reportedly affected the iPhone 5, an update is also expected to be released soon.
It remains to be seen whether this update will also address the reported jail-breaking capability of a tool called Evasion, which was created by a group of developer last week.
