Angels and ministers of grace defend me! My compulsion to beta test software has led to my iPhone's untimely demise. I installed anySIM from iPhone Dev Team, under the foolish assumption that it would work and do little harm to my dearly beloved. Everything seemed to be going fine until the unlock process completed. Then an error message popped up saying "Unlock Failed" and blathered on about not being able to update baseband settings.
Ok, I thought...the unlock procedure failed. No harm, no foul. I'll just back away slowly and not make eye contact. Then I noticed something that caused my Adams apple to move up and down in dramatic fashion; no AT&T logo or bars were visible in the service status indicator. Ruh roh. Don't panic, just restart. Did that, and still no signal. I can't make or receive calls at all. My iPhone is now the worlds most advanced paperweight.
I will keep you posted. In the mean time, if you happen to see a man wandering the streets clutching a black shiny object, in tears, that will be me.
[Update] Oh god, now I'm really starting to panic. I attempted to perform a restore via iTunes, and it failed. Now the bloody thing is stuck at the recovery mode yellow alert screen that reads "Please connect with iTunes". What a way to end the weekend.
[Update 2] And the clouds have parted. Pheww! Ok, I managed to do a full restore, bringing my formerly bricked iPhone back from the dead, and in working condition again. Excuse me while I change my underwear.
