I recently updated to 5.5 .901 it worked perfectly I had no problems. I updated from 5.5 .893 and I'm rooted. The update was working perfectly for a few days then all of the sudden I have no 3g. I don't believe this is the result of the new update. I contacted verizon and after doing several diagnostic tests they seem to think that I have a defective sim card. Their mailing me a new 1 I just want to see what you guys think. Here is what is weird I have the 3g icon but no conectivity however when I turn on wifi and get a connection to wifi the 3g then tries to connect. If anybody has any idea what is going on with my phone or any ideas on things I can try to fix this issue please let me know. This is what I've tried so far pulled the sim card toggled airplane mode pulled the battery done everything except a hard reset I even reinstalled the 5.5 .901. So tell me what you think.
