Game Store App in the app store?

Can anyone give me pointers where to find the Game Store app, or what I should search for in the app store. By Game Store I mean the computer game shop "Game" in the uk. I was told they have an app that gives you game trade in prices, but when I search game, I just get lots of games as answers. BTW it's for the iPhone, thanks.

IPhone 4S text tones don't work?

It seems to be a common problem from what I've read… But I was wondering if there was a solution. I've gotten a few texts and it didn't make a sound. I've read one thing that had to do with iCloud, but I'm not using iCloud…

Ok so I just bought a new iphone and I set everything up, but trying to ring O2 (my network), I couldnt contact them, as soon as I ring, It says calling, and immediately, call ended.
It does the same with every number, so I'm wondering is there a fix… Its literally 3 hours old: S

Any help please, would be pretty good.thanks
