I clicked on T-mobile and I noticed all of these other APN servers:
APN: wap.voicestream.cominternet2.voicestream.com
User Name And Password: guest (for the 2nd APN only) leave in blank
NEW APN: epc.tmobile.com no username or password
hiptop.t-mobile.com User Name: dummy Password: dummy
What's the difference on all of them? Which one is best? What works best for what?
