I just bought a sk3 on ebay for the heck of it, I'm regularly an iPhone user (unlocked). I only have a text plan on my iPhone, no data, IM or email. I have a proxy for those 
(ifailhard.com if you are wondering) I wanted to know what uses data on the sidekick? Email, IM, or neither? I remember tmobile used to use texts as IM and email, is that the case with the sk3?
