Updated to 3.1.3 and now bricked

[NLeo]

Well my iphone kept resetting last night so i woke up this morning and restored it to the 3.1.3 firmware. Well for the past 10 hours ive been trying to fix it and ive given up.Everytime i plug it into itunes it gives me a error saying Iphone cannot be restored (2).

Im thinking about bringing it to the apple store tomorrow but i got the phone a week after it came out so i doubt they will be of much help.

Ive tried dfu mode, and restore mode. As well as 2 different computers and operating systems.

So you're saying its out of warranty?
You got it a week after it came what model iphone?
If Applecare expired you will be able to get it replaced for $200.

Try disabling any firewalls/security software temporarily, as this may not be letting iTunes access it's verification server. Is it failing after verification? Are you using Windows? If your not, I wrote I guide a while ago that may get the phone to start. Try it if you can. Here it is.
