According to a report by German blog iFun, some carriers have already completed testing the iOS 6.1.1 update that addresses 3G performance issues faced by a number of carriers in Europe, who have also issued warnings to their subscribers not to upgrade to iOS 6.1, and Apple will soon roll out an OTA update carrying build number 10B145 (via 9to5Mac).
The source details that the issue was not just with 3G through carriers such as Vodafone and three in Austria, many users in Apple’s own forums complained of similar problems, degraded battery life, problems with Exchange support and more.
After ifun.de this information is already in version 6.1.1 of the night on Monday as “Testing Complete” and should be offered the iPhone community with little flow as a wireless update. Sources which are applicable in the past on the issue dates of iOS 6.0.2 and iOS 6.1 as well as the eradication of the “SMS spoofing problem” have informed, indicate the large 23MB update with UMTS-compatible.
A 23MB iOS 6.1.1 OTA update carrying build number 10B145 is expected to go live and address the bugs pretty soon.
