I bought a iPhone 4 from somebody and it's on 4.2.1 it was like brand new he used for like a 2 weeks or so I have had the phone for like 3 weeks what I wanna ask is is their a way I can find out if this phone has been jailbroken before?

Second question my girlfriend has her iPhone 4 on 4.1 is their a way to unlock her phone bc she don't want her blackberry no more lol.

Tiny umbrella download it it will tell you if you have any shshs saved if yes your phone has more than likely been jailbroken before.
And for hers no there is no unlock for 4.1 unless she has 1.59 baseband.

EDIT: yeah they guy never jailbroke his phone =/ lol
