I reset the phone default settings, and ServiceBooks don;t even come through anymore. The E-Mail Setup Wizard is gone as is the SMS/Text icon and BB Messenger icons. Gonna call RIM tomorrow with the T-Mobile rep.
Mine seems to be playing up since about 5pm (Irish time). Its now 10.30pm and still not working correctly. I am on O2 Ireland. For most of the evening it was showing lowercase gprs or edge and then it went to uppercase and I got about 18 messages and have been getting them on and off all evening. The annoying thing is it is showing in uppercase all evening but when I go into services status, it shows as not connected most of the time
Ok, well I now know what the issue is. After speaking to T-Mobile and RIM Tech Support, it turns out it is an issue with the Curve as well as some other BB devices. If you have the phone's WiFi on, this will cause the phone to freeze in WiFi mode. Even if you step out of a WiFi area, the phone will internally think it is still in WiFi. Therefore, you will not get e-mails sent and experience Browser problems.
After about 20 minutes with a RIM tech, he did his magic and reset my phone from their end...updated Service Books, and everything now works fine.
My suggestion, call your carrier BB support and they will troubleshooot some stuff and eventually get to RIM tech support.
