Question by Travis: iPhone Bricked. :[?
I had a perfectly working jailbroken 1.1.2 iPhone serviced by AT&T, practically new, got it for Christmas. Last night I saw a 1.1.3 Upgrader by Conceited Software in AppTapp Installer. So I downloaded it, installed it, and had a working 1.1.3 Jailbroken AT&T iPhone…. For about a minute. I proceeded to install BSD Subsystem and Customize, maybe another app or two, and my phone respringed with the connect to iTunes screen. So, thinking I might have to do a restore, or maybe activate it; probably the latter. So, I connect it to iTunes. iTunes came up with a message that said “There is a problem with your iPhone, and it may be damaged, please take your phone to the nearest Apple Store for repair.” Or something like that. So, thinking I can get around this, I try every known solution I could think of, I connected it to a Mac, a PC, tryed booting it in restore mode, etc, etc. (Which DIDNT HAPPEN???) So now, I’m asking for help, because only god knows what happened to my phone last night.

A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device that can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station.
In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones.
The first hand-held mobile phone was demonstrated by Dr Martin Cooper of Motorola in 1973, using a handset weighing around 1 kg.[1] In 1983, the DynaTAC 8000x was the first to be commercially available. In the twenty years from 1990 to 2011, worldwide mobile phone subscriptions grew from 12.4 million to over 5.6 billion, penetrating the developing economies and reaching the bottom of the economic pyramid.

I unlocked my iPhone with TMobile, and the night it happened I almost wanted to throw up. It sucks to waste 400.00 like THAT. There’s nothing you can do with it at this point, your best bet is that apple will take it back. Luckily, when I jailbroke mine, I did it early in the game, so they took the phones back, and I got full refund, but its impossible to return them now unless you think of a seriously good excuse. The phone isn’t worth anything at this point anymore. You can try jailbreaking it again, but I highly doubt it will :[
I’m sorry this happened to you.
