I, too, just bought an unlocked Treo 680. I can't answer the question about the Blackberry data plan, but I can tell you that T-Mobile has a team in the Blackberry/PDA support group that is dedicated to helping those of us who have unlocked Treos and other unlocked PDA devices. I got to a Level 3 tech last night who gave me the IP address and other settings. Just say "PDA support" when the automated system prompts, then ask the live person for the group that supports unlocked PDA's. |
