Losing Data connection
 

I've searched for this to see if there is a network problem, but really didn't find anything. I'm a USCC customer, and just updated my phone for 3g. The upgrade did effect the radio version. But since the upgrade, which was suppose to improve the radio, I've have been losing data connections a few times during the day. This doesn't occur every time, but always happened after the phone has been inactive for a while. This never occurred before the upgrade. Any USCC customers with similar experience? Does anyone know why this is happening?
