I had a 1.1.2 jailbroken iPhone and decided to upgrade to 1.1.3 using the dev team download on installer.

I did what was required and downloaded the latest BHD subsystem blah blah blah.

The download worked and my iPhone was on 1.1.3, i then went into installer and it said i needed to update installer. I clicked on update installer and my phone went to a start screen. (the one were there is a itunes logo and a lead going to it).

I then connected it to my pc an ran itunes and this is what itunes said.

"There is a problem with your iPhone"
"The iPhone you connected may be damaged and cannot be activated for service"

I need big help on this one and I'm sorry if this problem has accured before but i dont know what to put into the search bar.
