I've been having the same problem for a couple weeks now on my Bionic. I've had my Bionic since the day it was released. Never had any issues with data connection unlike many others with the same phone. Always updated the firmware every time it was released OTA. Have been on .902 rooted since it was released and never ever had a data connection problem. So its not related to the phone. It seems to be Verizon network related. But its getting frustrating....Verizon needs to fix something!!
