iPhone Stuck On Apple Logo

I have a unlocked iPhone and had issues with it because the charge did not show up when I plugged it in and would not connect to computer so I tried to restore all and ended up with it locked on apple logo with the little spinning wheel that stops and starts moving very slow until it reboots itself. I have done the 2 button hold down till I get it to the connect to iTunes logo but still does not connect to computer or iTunes (just not recognized) I know the dock works because when I shut it down completely and then connect the USB data cable it turns on and goes to apple logo. I have a Windows 7 OS and have tried Blackra1n but will not work saying it's missing something so I tried Limera1n and it worked but still waiting for device no matter how I boot the iPhone up it does not find it.

Is this thing bricked?

Forgot to mention it's on 3.1 software.

Nope that did nothing just took me to the iTunes plug in logo and stayed there, what do you mean try jailbraking forums directly?
Sorry I'm new here and you may say I'm a newbie

It does go into DFU mode but it won't connect to computer or iTunes, it just is not recognized and makes no sound when connected to the computer, it just has the connect to iTunes logo on it and does nothing.

Done that but still the computer nor iTunes will show the connection

When I have the iphone turned off and plug it into the wall jack or the computer the apple logo pops up and does not get recognized by my computer or any of the other 3 I have here, tried deleteing and installing new itunes on other computer as well and also tried rebooting the computer while the USB is still connected and still nothing.
I think it's bricked.
