I have unlocked my phone to run tmobile. Everything is great -- wifi works well at home -- the Edge does not work other than sending and receiving emails. I have the T zones plan (had it on my cell before the iPhone). I have filled in the APN with wap.voicestream.com. Username and password are blank. I have strong Tmobile coverage where I am - and the tzones always worked fine on my cell. Any suggestions? Thanks!
