iPhone 3g help please?

I got an iPhone 3g from my uncle, already unlocked/jailbroken. But I wanted to go to iTunes and restore it because all of my uncle's content is on it.. But when I connected it to my laptop, it didn't appear on iTunes under devices.. Isn't it suppose to? Why isn't it?

So then I tried to reset it from 'Settings'. The apple logo appeared in the middle and there was a bar on the bottom and it went full after about 20 minutes, and then another bar came and it went full after about a minute. But then a pineapple appeared at the bottom and it's been there for the past 45 minutes. The screen has blinked three times where it turns white for a split second and then it goes back to the pineapple screen like I mentioned before. What's going on?? Someone please help!
