I have a T-Mobile 9700 on Simple Mobile, since a few weeks ago I am having some issues with the service.
I have 5 email accounts, if I read/delete messages on my phone it will update on the accounts, but if I read/delete from a computer they won't update on the phone.
Also, if I am connected to a WiFi and leave the WiFi coverage, the 3G won't take over the connection to BIS, I'll have to turn off/on the Mobile to get it to connect.
Note: I used my phone PIN to request PB developer signature keys, does it affect the BIS?
