Hello,

I have an unlock/jailbroken iPhone 3G and Im trying to insert my T-Mobile SIM card and it wont fit, but its just like the one from AT&T
 
I got it to go in....I have another question. How can I restore my iPhone without having to update?
 
I'm going to go ahead and guess that you haven't searched the forums -- so we'll give you some time to go do that now.
 
I have search the forum and have not found anything if not I wouldn't be asking
 
Won't fit... you're putting it in wrong, or it's not a SIM card. Take a picture of it.

I got the SIM to go in. My other question was on how to restore my iPhone 3G without having to update it to 2.2.1
 
Once I unzip the file which file do I select cause it wont let me select any of the files...
 
You don't need to unzip anything??
After its downloaded save it to your desktop. Then in iTunes hold shift and click "restore" and select the firmware from your desktop.

easy peasy lemon squeezy
 
Thanks what I did before unzipping the file and I wouldn't let me either
 
Okay, you're on a Mac, soooo....

In Safari, go to "Safari" in the menu bar, select "Preferences", select the "General" tab, uncheck "Open safe files after downloading" then re-download the firmware you want. This will keep the firmware in once piece as a "*.ipsw.zip" file. Go to your downloads folder (or wherever you saved the file) and rename the extension to remove the ".zip" portion to be left with "(firmwarename).ipsw" . This should change the icon to a blue and white cube.

Now, in iTunes, plug your iPhone in and hold "Option (alt)" key while clicking on "Restore" in the iPhone pane of iTunes. This will bring up a Finder window. Find your newly renamed .ipsw file, and open it.

This will restore the iPhone with the selected firmware (I assume 2.2). After this is done, re-apply the jailbreak and unlock. Simple as that.
