Found an Iphone 4, How to hacktivate?

[PeterJuhasz]

k, so i found an iphone 4, Ive had a lot of things taken from me, so im keeping it, ( i dont want any moral lessons, there should be a religion topic somewhere on yahoo answers) so yeah, ive restored it, so its running on whatever the newest version currently is, and its saying insert a valid sim with no pinlock to activate, ive tried alot of hacktivate things, limerain, green poison, redsn0w, and they didnt do the trick, so can someone help me out, or maybe tell me general mistakes with the three jailbreak/activation softwares up there. or tell me an even better one,

10 points to who helps me out, cheers
