Jailbreak the iPhone on 1.1.1 firmware for T-Mobile
 Apple , EDGE , iPhone , T-Mobile
This article has been edited and updated for the latest 1.1.2 firmware
- Step 1. if you are using 1.1.2 you must downgrade to 1.1.1 — which isn’t a big deal since 1.1.2 only adds language support. Sorry there are more complicated ways of solving this dilemma, but this is the simplest solution.
- Step 2. using a wifi connected iPhone simply visit jailbreakme.com in safari (see this website if your iphone is not activated and you cannot get in to safari.)
- Step 3. wait for the jailbreak to install and restart your iphone. You should now see a new icon titled “installer” this will allow you to download many apps.
- Step 4. if T-Mobile service is not automatically indicated install anysim from installer.
Tip: for custom backgrounds and themes try installing summerboard.

Thanks this guide is the simplest way I have found to unlock the iphone. However I needed to use this guide: http://hackint0sh.org/forum/showthread.php?t=15272 to downgrade. If you just try to downgrade your iphone without doing it that way you will get a 1015 error.
On a side note I do not think Apple is going in the right direction with the iPhone. I sometimes wonder if Microsoft made the iPhone… Actually nevermind if MS made the iPhone it would probably allow developers to develop! Yet I suppose if MS made a phone it would suck just a tad worse. Gosh what is wrong with these companies!
