I used the Carlos method to unlock a 1.0.2. i updated my installer.app to 3.0 from 2.63 (via wi-fi).

Now everytime i try to open it it just goes back to the homescreen.

Is there anyway to rectify this? If not please suggest a way to manually remove installer (tried iBricker - doesn't show up in that).

Also, is it safe to use Itunes 7.4.3 (currently use with an unlocked 1.0.2?
