Downloading and browsing on wifi, without a data plan, can be done even on a prepaid plan with T-Mobile (or no plan at all if you have a SIM and set the phone to wifi-only)
Settings > Advanced Settings >Browser
Change to "hotspots"
Browser will work, downloads work for programs such as Opera and Windows Live Search and dowloading updates for programs such as Documents to Go. No applications requiring BB services will work such as BB App World and Google Maps.
The same is true for postpaid T-Mobile without a dataplan, although you can call to get blackberry-enabled for MMS for free. This will change the display from uma/edge to UMA/EDGE, but the only additional function is sending and receiving MMS at any time. AIM and other instant messaging programs will not function.
Prior to 6-1-09, you could call T-Mobile and say that AIM didn't work and they would enable that service for your line of service, which then allowed all applications be downloaded and function such as BB App World and Google Maps. Most programs will not function off wifi (while on EDGE), except for Google Maps, which charges data, but in small amounts that typically do not add up to 1 MB in a month.
Our family has two 8220s on postpaid T-Mobile with no data plan, we have an unlimited text plan. One was Blackberry-enabled prior to 6-1-09 and can do everything on wifi including email, and 3rd party apps and it can also use AIM/IM on EDGE and Google Maps on EDGE. The other was Blackberry-enabled after 6-1-09 and can browse/download on wifi, but it cannot use AIM/IM at any time and it cannot use 3rd party apps, except for programs such as Opera and Live Search. It can also send/receive MMS.
I also have a 8320 using a pre-paid SIM. It can browse/download on wifi, but it cannot do MMS or AIM/IM at any time and it cannot use 3rd party apps, except for programs such as Opera and Live Search. If I put the SIM in it from the 8220 that was Blackberry-enabled prior to 6-1-09, it can do everything.
