Hi i am using an iPhone 5 since 2 days now. Iam on T-mobile in Germany. I am on this provider since the first iPhone and was upgrading from a iPhone 4. I experience serious problems with my cellular connection while calling. Often i can not even hear my opponent even having 5 bricks of service. Friends of me, also on t-mobile, on their iPhones 4s and 4 are fine sitting right next to me. I have seen that some people have the same problem in german forums but haven't seen it here yet . Its really frustrating since the phone does everything but "phoning" 
Anybody with the same issue ? I don't know whether this is hardware or software related.
PS: When talking to somebody it sounds like the opponent is cut away or soundless like a robot(ish)
thanks for any supplies. greetings
