Yeah, you heard it right! The best guide ever, just buy an iPhone from AAPL or ATT and sit there in the store and unlock it – the simplest it can ever get! You need WiFi btb!!No Mac or PC required! Unlock the iPhone straight out of the box! Save the money from investing in Unlocking software and use it wisely 😉

1. Slide for Emergency calls, dial *#307# press call, now use the back button on the top of your screen to remove *#307# , now enter 0 , press call, press answer, press hold, press decline. Now you get to the contact list.

2. Push contacts and add a new contact and type in “prefs://11” as web-address and “http://jailbreakme.com” as an additional URL.

4. When you tap “prefs://11” you can now select your preferred WiFi gateway. I recommend an open WiFi network 🙂

5. Now press the home button and move the slider to the dial-pad. Repeat step 1 till you can access contacts.

6. Now you can go back to the contact list by Dialing 0, push call, then answer, then contacts, then hit the “http://jailbreakme.com” web address you typed in.

7. Scroll down to the bottom, click “Install AppSnapp”. Safari will exit and you’ll return to your springboard. Wait for the phone to reboot. Your phone is now jailbroken and Installer.app is ready to be explored 😉 (If it refuses to install, try installing it till you see the downloading thingy on the screen! It took more than 6 attempts on one of my friend’s iPhone!)

Well, at this stage, your iPhone should be activated partially – Cingular should work just fine! All the other networks should do a little tweaking to use your iPhone as a phone!

Unlock your iPhone :

Launch Installer.app and then click on “Sources” – > “Edit” – > “Add” – > Type i.unlock.no after http:// – > “Ok” -> Now anySIM 1.1.1 should show under “Unlocking Tools” – > Click on it and install it! You can now see anySIM icon on the Homescreen. Click on it and follow the instructions! Vodafone, T-mobile, 3 and what not, everyone can join the bandwagon now!!
