It’s D-Day for those who have unlocked iPhones and wish to update to the latest firmware. iPhone Firmware 1.1.1 has just been released and Gizmodo has a run down of the updates and what it can do to your modified iPhone.

The good news is it won’t technically brick your iPhone. Realistically, however, it will bring you back to the activation screen thus rendering it useless from there on end. The Dev Team is currently trying to find out what can be done so that you can benefit from the updates while maintaining the unlocked status of your iPhone. For now, as they say, it’s best to keep away from the update.

If you want to check out the progress of the Dev Team, head on over to Gizmodo to keep abreast of the latest developments.
