Either use an official provider or buy a PiggyBag SIM - which might give you some functionality.

What does all this mean?

If you don't know, it probably doesn't apply to you. Which carrier do you use your iPhone on. This is only if you want to use your phone on a different carrier to the one it's locked too.

how to jailbreak my brand new 16g, 3g iphone if my iphone version 2.2.1 (5H11)?and i dnt see any firware 1.2.2.2.1_5H11.ipsw, and also can i downgrande this version 2.2.1(5H11) of my iphone or not? need help??? please!! and im using window XP

u can't yet jailbreak the FW 2.2.1 Do u guys REALLY READ the article ?? +_+

I guess not...... ¬_______¬

If you have FW 2.21 then you have BB 2.30.03 - you can't downgrade the BaseBand so cannot use YellowSn0w. A jailbrake should be released soon.

But i still don't get it, it says the 3G will not work if it's updated and that the 2G has remained untouched for 8 months; does this mean that i can upgrade my 2G to 2.2.1 and it will be ok? Will Quickpwn (the last version) work on this update? Sorry if the answer is obvious...

on the dev team website is looks like iphone 2g's that have been unlocked before can do this update, but can't be guaranteed a jailbreak, but the unlock will remain. Still haven't done this - awaiting further instructions - iphone 2g

@marco, the 2G iPhone will always be unlockable if it can be jailbroken. The 2.2.1 doesn't prevent jailbreaking but you will have to wait for a new version of PwnageTool or QuickPwn before updating. The iPhone 3G on the other hand is not currently unlockable with 2.2.1 even if jailbroken.

No, no, no and NO. that's it.

Watch the video on the Dev Team's blog. You can upgrade your FW on the Touch but the jailbrake is not available yet. They are working on it.
