My App Store disappeared, how do I get t back?

About a week ago my App Store on my month-old iPhone 4 was no longer on my home page. I mostly have music and pictures on my phone, no apps really and no games, so I don't use it that much. Anyway it's not on my screen, I've searched it on my iPhone I can't find it anywhere. Could it have been deleted somehow? Where did it go? How can I get it back?

Really confused on what to get, need opinions

Ok basically my boyfriend is getting me really nice jewlerry and a book for Christmas and maybe an iPhone case, but I'm confused as what to get him!

I was thinking eaither one or two of these:

Dynamo (it's a DVD I noticed he said he loved)
Gavin and Stacy series one or two or like a random series (he really likes Gavin and Stacy) (its. A tv series)
A watch (he said he hates having to get his phone out in lessons to check time)
Family guy season 10?

He's a typical guy and I'm not sure what to get him:'( my budget is about £25 because I'm like broke.

But any suggestions would be highly appreciated.

My iPhone 4S takes pictures of my pocket?

Sometimes when I put my iPhone in my pocket and I try to change the music volume with my headset's buttons, the volume doesn't change. Then I will take the phone out of my pocket and if I press the home button it displays the camera app. I never get my lock screen, just straight to the camera app. I'm currently running iOS 5.1.1 jailbroken. Anyone know what's happening?

I think I'm getting an iPhone and I was wondering which data plan I should choose (AT&T)
