Strange, maybe it's a carrier difference... I'm listening to Pandora radio while chatting on AIM while typing this reply, all on wifi and no data plan. Installed all my apps straight from the web, no memory card or pc. I use T-mobile. Everything from Google Maps to Pyont work great.

Owning a smart phone without a data plan is pointless. I think most people who do this just want to look cool. Every phone has a calendar so saying you use a smart phone for something like that doesn't cut it.
with this program you copy and paste the OTA link for a theme/program whatever and it'll start downloading it to your PC
then you can put the jad/cod files onto a memory card
after doing so, go to your media folder and hit the BB button and select explore and select the jad file that u placed to start installing
