X10 on AT&T in US Been working fine for about 2 months with data, MMS and 3G in (North Carolina) 3 POP accounts and 1 Exchange account all sync'd up and working. Then, on Sat at around 7:30pm I realized the phone was no longer getting emails (Outlook was chiming away but phone on desk eerily quite) Picked it up and noticed 3G indicator wasn't there. Recycled power - No change Updated firmware to R2BA020 - No change The APN settings are correct and haven't been changed since working. AT&T Unlimited data plan is in good standing. So, although nothing has changed, I can no longer get any data (email/web/facebook/etc.) nor can I send or receive MMS. All of these work if I turn WiFi on but not over the cell network. Any ideas?
