I've been reading the forums and everyone says my apn needs to be wap.voicestream.com, i changed it to that, and i still get the same invalid apn # error... i have tmobile and a curve 8310, any help?

Check this compiled list of TCP/APN settings from various carriers. There are a couple alternates for Tmobile that may work for you:
TCP, APN, WAP, Gateway and Port Carrier Settings - PinStack.com Forums

Okay, everything checked out, i've tried all of the apn addresses, and they're not working... and maybe i should've asked this first... should it make a difference that this was a suncom phone, and still has a suncom sim card?

Also try Berry Tunes support - they are very responsive and might be able to help.



Good luck...love my Berry Tunes, don't know how I'd survive w/out it!
