Have you tried to activate your iPhone to no avail? Are you holding a US$299 brick in your hand? Here’s what you do. When activating your iPhone (or just upgrading to 2.0 software), if you get an error message on your phone, DO NOT UNPLUG IT. That will restart the entire process.
Instead, just wait. Leave your phone be and don’t close iTunes.
We’ve successfully activated five different iPhone 3Gs with error screens just by letting them sit plugged in for anywhere from 10 to 15 minutes. Hopefully that might work for you, too.

Wednesday, November 26, 2008 at 10:15 PMi didn’t know that and i upgraded my iPhone 3G to 2.2 and i found the same screen up there but my sim wasn’t in my iPhone, and i unplugged it, i found a text says
No SIM cared installed
insert a valid SIM with no PIN lock to activate iPhone…
and now i’m really in a big trouble it’s not working since the morning.
P.S: i bought it from Honk Kong and i’m living in United Arab Emirates right now and i don’t have an iTunes account yet..
What should i do to fix this trouble?

Monday, August 3, 2009 at 2:28 PMThe same error has occurred on my phone. I already unplugged it before I found this site and I turned it off for awhile but I turned it back on to find the same locked screen. So now I’ve had it sit plugged in for awhile but nothing has happened. I’m not contracted with ATT, I’m with t-mobile so calling ATT wouldn’t help me much. Is there anything else I could try?

Thursday, December 8, 2011 at 10:14 AMHey Frank sounds like your phone is bricked , 2 ways i know how to fix that 1st one turn phone off hold home button and plug usb cable itunes should recognize and ask you to restore and update go ahead and do it , that should work. 2nd their is a program called tinyumbrella download it and installe it and hit exit recovery if it reads your phone , more likely the 1st one will work.
