so what I did last Thursday was calling customer care and asking for tech support. I told them that they have tried to fix the data connection issue but they have failed. Since they had replaced my phone before and they knew the new phone is not going to fix the problem, they offered me a HTC Rezound. it is basically an upgrade to Bionic. it has a faster processor and better screen. ICS is already on it(http://geekaphone.com/compare/HTC-Rezound-vs-Motorola-DROID-BIONIC). I looked around to see if there is any known issue with it, but it seems that the ics update have no problem so far. I think your guys should call and ask for you phone to be changed.

good luck .
