iOS 6.1 3G coverage really bad
So I had perfect 3G coverage, speeds and a stable connection before
Then I updated my 4S to iOS 6.1
Since then, even though the 3G icon is showing, connection will be inaccessible every other minute. Connection became really unstable. For instance, in games or apps, warning will pop: "Internet connection lost" even though i'm in full coverage area AND 3G icon is showing.
This is really, really bad. iOS 6.1 destroyed my iPhones 3G connectivity. Can't use my 4S like this. Please fix ASAP, is not a user or settings problem, iOS 6.1 broke my phone.
iPhone 4S, iOS 6.1
