anyone encountering this type of problems? the phone was in perfect working order as of this morning. i had to reboot due to sim card error. i am not sure what to do now.
btw, the phone is set to WIFI preferred in the setting.
There are two issues currently. Numerous users (myself included) are currently experiencing a full UMA outage. If you go to Options->WiFi Connections->Wi-Fi Diagnostics you will likely see a "ISP or T-Mobile network error". The hand-off issue is a known issue affecting most if not all users in California. It is not clear if the fix will be to the towers or handset, but T-Mobile doesn't expect that to be fixed until October 22nd.
