Apple iDevice users can expect a small over-the-air update this week to sort out connection problems that affected users with the 4S handset, German language online magazine iFun reports.
The 6.1.1 iOS update is 23 megabytes in size and has been tested by carriers, according to iFun.
Vodafone's British arm warned its customers over the weekend with an SMS alert and support forum post that the 6.1 update may cause problems on iPhone 4S handsets, and asked people to hold off installing it.
Soon after, Austrian mobile telco 3 also asked its customers not to install the 6.1 update, after its support team confirmed it would cause connection problems.
Users who have installed the 6.1 update are also complaining in Apple support forums about overheating devices and reduced battery life. At this stage, it isn't known if the 6.1.1 update will sort out those problems too.
Enterprise users with iPhones connecting to Microsoft Exchange servers with the ActiveSync protocol report that doing so causes a loop that makes log files grow to an enormous size.
Again, it remains to be seen if Apple's 6.1.1 update fixes the Exchange log file generation problem.
