Ok, I havnt seen anyone on this threat mention this so here goes: I currently have the droid Charge along with about 30 other company employees...several of my friends also have the thunderbolt.
This data connectivity issue is across the board with the charge, thunderbolt, and now the bionic. What I mean by data connectivity is,,,the roaming from 4g to 3g to 1x to nothing. You reboot the phone and you instantly get a 4g signal for an unknown period of time and then its starts going thr the same cycle again. I have had this problem in Dayton Ohio back in the spring when it was a 3g area only and now since we have had the 4g "Upgrade" yeah right.
On my droid charge I will also not receive txt, my txt will not be received by others (despite a confirmation of delivery). People will call my phone and it will not ring, will sometimes send the caller straight to voicemail and sometimes not even register as a missed call on my phone.
The above noted problems seem to be across the board with verizons new 4 g phones. Even on the days that your phone seems to work halfway decent, you have to keep it locked into cdma mode so that you can get a full days use out of the battery.
If you are within the 15 return time for the bionic, I strongly suggest you do so and reactivate your old phone. I am not hating on android, verizon, or anybody else,,,just what I have seen across the board. Although, I should be hating on verizon. After many contacts with them; they are acting like it is the individual phones problem...I believe they are aware of the problem and they know it is huge.
Dont get locked into to a nightmare like i did with the droid charge. I was told everything from ...its that individual phone, to there is an update coming out soon to fix it, to "once your city recieves 4g all these issues will go away..
Please dont take my word for it....look up the droid charge, and thunderbolt forums...not trying to sell anything here.
