Any of you guys out there take the plunge and jailbreak it? I found a site that claims to do it for you (http://jailbreakme.com), but I have to admit I don't want to void my warranty.

I did a friend of mines... it worked. I am on T-Mobile and everything worked with my SIM in there... now just gotta wait until he gets a new phone so I can bum his IPhone lol
