I am about to purchase an ipad2 either in store or on ebay.. and i am just looking for the ipad 2 wifi only 16gb, my question is, will i be able to get wi-fi access right off the bat without having to do anything but turning it on? espesially if i order it off ebay? like do i need to pay for some sort of data plan? or what, mainly wondering so i can jailbreak and unlock it. Thanks much.
