My brand new unlocked/unbranded Treo 650 arrived today and I'm so happy. I made a switch to the Blackberry and regretted it.

Unfortunately, in the switch I gave up my grandfathered $19.99/month T-mobile unlimited data plan, and got the $19.99/month Blackberry plan, also unlimited data. Then T-Mobile started bundling Hotspots with their unlimited data plan for $29.99. The Treo doesn't have wifi, so why should I pay $10/month for something I can't use?

The Treo won't acquire a GPRS signal straight out of the box using my current Blackberry plan. Has anyone found a way of doing this? Or am I doomed to spending $10/month for wifi Hotspots without any way to use it?
