iPhone 2.2 is out but the dev team is warning people not to download it until they know what it does. There is a possibility if your phone is unlocked it will break this. The other reason they cite is if you have a 3G and want a software unlock in the future you may ruin your chances if you update now.

Just putting this out there so people think about it before they hit the update button. I would really give it time to see what others are saying before doing the update. If you do the update anyway then please report what your results were.

I am also very curious to see if 2.2 breaks the SIM card unlocks that are out there. I am on a locked 3G so would like to use one of these for my phone when I am in Thailand.

Just restored a non-responsive iPhone, put my AIS simcard into it, and iTunes says:

the sim card inserted in this iphone does not appear to be supported

So I guess the simlock is still there

update: just read the answer from post below.heheh.thanks anyway.

does it make the iphone locked if you have a hk unlock iphone and tried to restore the firmware 2.1 from itunes?

Have a look at this earlier thread. Search is your friend.

HK iPhone thread

The news is out from DevTeam: you CAN jailbreak 2.2 now, but since the baseband is changed, your previously unlocked iPhone will no longer work as a phone. This apparently includes both soft unlocks and SIM unlocks.

If you have a factory SIM Free or factory unlocked iPhone (such as the one sold in HKG), your iPhone's unlocked capability will NOT be affected.

Details from DevTeam here.
