Problem with Itunes purchase?

I recently purchased an album on Itunes and I wanted every song on the album except for one. So I purchased the whole album and then tried to delete the one song that I didn't want. Now, the song still appears on my iphone but the writing is in grey instead of black and I can't click it. Is there any way to fix this? Secondly, because of this issue, my iphone has not synced properly with my computer. Is there any way to fix this?

I forgot my iPhone passcode, how can I do a factory reset or restore it?

I don't have the computer I synced the iPhone to anymore, so I can't go into iTunes. Is there like a program to bypass this? Or a combination of buttons? I've tried many things to restore it, but It all involves me going into iTunes. Please help?

Added (1). To the people that have responded saying "It doesn't need to be the comp you synced it to" it does, it won't let me connect because it gives me an error saying "This iPhone is locked, you need to enter the passcode, and try again" And I kinda don't remember my passcode

I accidentally locked my iphone?

Long story short. I bought an unlocked iPhone 3g from this guy on eBay. The other day when I was going through the settings, I accidentally locked it by doing the SIM Pin option on the phone setting.

Iphone 4S App store isn't working?

I just got my I Phone 4S a few days ago, and it was perfectly normal, all the apps were working. I haven't downloaded any apps either. So when I tried opening my app store today on my I Phone 4S, I realized that it wouldn't work. It was like the screen had froze. It wouldn't respond to any of my touches and it just completely didn't work. Any ideas on how to fix this?
