i want to buy an iphone 3gs from ebay and i got all excited cause the prices went down a bit, then it hit me that theres this new thing with the 3gs.....something about iboot..???? not even sure....but its somehting that the new 3gs has that causes alot of problems when jailbreking. i need to jailbreak cause i need to unlock, so it is a problem for me. i want to know how i can figure out if i am getting a safe iphone 3gs or the problematic one, or are all the 3gs phone easily jailbreakable?

I hope u get what im trying to say
