[ollie_12318]

Okay so, being the idiot i am i updated my iphone to 3.1.3 software version, no my sim card is not supported.

I've been looking around and everywhere is telling me telling me that it's not possible to unlock it.

If that's true, then can i somehow restore my iphone to an older software version??

Please let me know! thanks guys

What you have read is correct. You won't be able to downgrade the baseband even if you could get the firmware downgraded.

And i have an iPhone 3g by the way.. does that still not work then?

Is there anything I can do?

thanks

Doesn't matter which phone model, you've upgraded the baseband and you can't downgrade that. (except for 2G)
