I am sure you are all aware of the recent Iphone problems (typed with a rye smile). I experience a similar thing with the hero on orange. My home seems to have a really weak signal normally 1 or 2 bars and i can only get gprs here at best of times, when at home if i am texting one handed holding the phone at the bottom as you do i will totally loose the signal until i hold the phone differently then i carry on with text message. This to me is not a big problem and the phone seems to retain the signal at 2 bars when left sitting idle. I just wonder if anyone else has noticed the similar grip of death?
