How to Unlock iPhone 3G/3GS Baseband 05.11.07 without Blackra1n

by Alvin on November 7, 2009

If your iPhone 3G/3GS was previously jailbroken using blackra1n and the blackra1n app was removed or deleted from the home screen, you will need to jailbreak again to install blackra1n. With cydia installer, if you do not prefer to jailbreak with blackra1n rc3 again, now you can install the blacksn0w to unlock the baseband 05.11.07 on your iPhone 3G/3GS. But, you can follow this step-by-step guide if you wish to jailbreak and unlock your iPhone 3G/3GS from scratch.

1. Launch cydia installer and navigate to “Manage” tab. Then, select “Source”.

2. Tap “Edit” follow by “Add” buttons.

I have followed every step possible. I have an 8gig iphone 3g with firmware 3.1.2 and baseband of 05.11.07 and it won’t find my tmobile service even when i turn off my 3g. Any ideas? Please let me know

Hi Ferdinand,

I would suggest you to do a clean restore to your iPhone 3G, then jailbreak and unlock it again.

Hope it helps…
