Anyone know if i will be able to unlock the 4g when i get it and use it in guam, i don't really understand unlocking very much, but we're moving to Guam in July and i already have the 4 on preorder... Can anyone help me?
yes obviously i know this since it's preordered but i was wondering if it will be possible and if it will be much different than unlocking the previous models. like i said i don't know much about unlocking....
There might be more to it than just the baseband. For example the 3GS introduced the signature signing system with apple's servers. They might have introduced another security mechanism in the i4 to make it even harder to jailbreak/unlock.
And don't forget that the i4 uses the same smaller SIM card that the iPad uses, so if your carrier of choice doesn't support that you're out of luck even if it is unlocked.
