now I have 1.0.2 in my iPhone Unlocked
I want to upgrade to 1.1.1 and again unlock for anysim.is this possible or not.
If possible can any one tell me how to do.
ok thanks

As far as I know, it's possible to jailbreak but not unlock it. I think unlocking can only be made on fresh 1.1.1 phones, not upgraded ones.
Need 2 wait a bit...
