I have a unlocked v3 and I can't use the internet. When I try to connect to it, it says GPRS Network is not available. Also I have tried to use mpt to add ringers to my phone. I can get photos, videos, update contact info. etc, but when I transfer ringers to the phone it says that it was sent to the phone but they are not showing up. I sent them to the correct folder. It was working before. I don't know what has happened that it's not working anymore. Please help.
