Yo !!! You people rule!! I'm from Macedonia and i have an iPhone 3G, i used it with turbosim card but it was B A D!! so i said let me try this... and it really works!! thakns u saved me 30 euros !!

Thanks for the tutorial, worked like a charm i can finally get rid of my annoying turbosim!

For me changing providers was easy. In Canada there are two providers that have the iPhone Fido and Rogers. I had a Fido iPhone. When I switched my provider to Rogers my iPhone would not work with my new sim card. So I put the Rogers sim in my iPhone and went to the Apple store. I told them that that battery in my phone wasn't working right. They just replaced the whole phone and because they thought it was a Rogers phone because of the sim card I now have a working Rogers iPhone. No unlock required.

Hey Folks, I have an Iphone 3g version 2.2.1 firmware 2.30.03 and a bootversion 5.08 I succesfully jailbreaked and succesfully downgraded the baseband to 2.28.00 Then I installed yellowsn0w to unlock and... it's still locked... have tried it 3 times from beginning to end now, not knowing what I did wrong... anyway my main issue is that my original T-Mobile sim card doesn't work anymore neither! so it's nothing more than a IPod Touch right now... please help!

If your not bothered about unlock can't you restore from backup

I'm new to this. I have both mac & windows vista &iphone 3g. What is the status to jailbreak & unlock with the latest firmware? I'm confused on this & don't want to try anything in case I wreck up my phone. Is a card such as rebel sim better for me? Help!

I have a 2g iphone that was on 2.2.1 and I lowered it to 2.2. It has been jailbroken with quickpwn, and I also put the yellowsn0w app on with Cydia. After cydia installs it, I don't see any new icons. I've tried toggle airplane mode, reboot, etc. After switching to a TMOBILE SIM, THE PHONE BRICKS ITSELF AGAIN WANTING TO CONNECT TO ITUNES. Works fine with ATT sim card, has not detected any other simcard. Help!

As far as I can remember you don't need yellowsn0w with 2g I think you are following 3g guide.Do the jailbreak again but remember to tick activate box.You don't need to restore in iTunes b4 you redo the jailbreak make sure u use the 2g guide

I did but Boo Neuter didn't run, any ideas as to why or how to force it?

I was able to get Boot to load this time around. However when the iphone comes back on I still get the same message of "Different SIM detected, please connect to itunes"

Are you doing the jailbreak with that sim card installed I think you should do. Try it anyway and remember to tick activate then if that fails start again from the beginning of the how to.
