I have upgraded my iPhone 4s to ios 6.3.1, since then I cannot use my phone because it refuses to accept my SIM Card PIN number (3 false attempts) and unblocking with PUK (also considers false). Has anybody experience a similar problem? My operator is T-Mobile Germany

iPhone 4S, iOS 6.1.3, ios 6.3.1
