[junii0r]

HEY ALL!!

So on Sunday i had to re download and install my FB app. while installing it had got stuck for a long time so i powered off/on my phone and it got stuck on the apple logo...for 2hrs...

so i just put in in dfu mode and plug it into itunes to do a full restore and the whole entire process went as normal, i even got the "Your phone has bee fully restored" pop up screen...

but here comes the problem..

itunes now doesn't read my device i get this messege "There is a problem with your Iphone.." (while my phone has a image of the itunes/usb screen)

i have already tried the following..

full restore (10x's)
took it to best buy. no help.
called apple. no help

i don't now what else to do. i am trying my hardest to find help before i have to drive 2hrs to the nearest apple store but no luck as of yet..

I'm running the latest iphone 4 software. this software hasn't been jailbroken. i have a PC running windows 7 and am up to date to date with the itunes software as well...

i would greatly appreciate any help that i can get.
