IPod Questions Again!?

Hello Everyone, I live in lebanon and when people purshase the iPhone They pay 900$ Cuz it's unlocked and works with lebanese SIM Card And services. So A Friend Of Mine Updated The iPhone And It Locked It Self And Can't READ SIM So She Went I Fixed It In A Cellphone Shop In Lebanon. So I'm Geting A Shiny iPod Touch 3rg Generation For Christmas So IF future updates came and i updated them by downloading them rapidshare... (not buying them) would it be a problem! or would it work fine - this question is iPod Touch User (1,2,3 gen) who exeprienced this. please i need an answer to see if i can update it for free!
