(adsbygoogle = window.adsbygoogle || []).push({}); Are there any ways how you can mod your name on mw3? I don't know much about that subject so... :/ (ps3 slim user, so i got no jailbreak, neither an e3 flasher)

No, if you don't got jailbreak on your PS3 you won't be able to change names, flashes etc.
And if you don't got a E3 Flasher then i'm sorry, because you can't mod anything online without jailbreak, maybe in some games but not in many though.

Best regards, Lukas.
