iPhone Dev-Team has released new information on the free carrier unlock software package known as ultrasn0w. Now iPhone 3G and iPhone 3GS devices running baseband versions 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00 are unlockable after jailbreaking. iPhone Dev-Team includes detailed ultrasn0w information in their recent Ultra-recycle blog post.

Running iOS 4.2.1 on your iPhone 3G/3GS? Updating your iPhone baseband to 06.15.00 using iPad 3.2.2 firmware actually makes the device unlockable for use on carriers other than AT&T Mobility. Dev-Team has developed a PwnageTool 4.1.3 Unlock Edition that will update the 3G/3GS baseband, and the group is working on a new version of redsn0w that will add this functionality for Windows users.

You may have heard that Apple now offers the Find My iPhone service for free to iPhone 4 owners who have installed the iOS 4.2 update. When set up properly, the service locates and even sends messages to the lost device. Find My iPhone can also remotely lock or erase your iPhone.

Now that redsn0w has been updated to jailbreak iOS 4.2.1 you may be wondering what's involved in actually jailbreaking your iPhone. Here are some tips and instructions to help.
