Should i buy a case for my iphone 4s?

When i first got it some lady put a case on it for me at the mall and when i got home i noticed some light scratches on the side and i think the cass scratched it. Should i even bother buying a case? I think it looks better without it but its fragile feeling so i don't know i feel like i should sometimes because i'm a bit paranoid it will get scratched when i set it down on a table or something.

My iphone4 was dipped in water for 3 secs

My son dipped my iphone in water for like 3 seconds, so I did the rice trick. I let it stay in there overnight, blew dry it with cool air. It worked for a little bit but it was so slow so I decided to update it and maybe restore it. But during the "backing up" step, my phone was vibrating non-stop so I did a hard reset, it stopped but then the nxt thing happened. My phone's screen all of a sudden turned blue and now stuck on a black screen with a little light like it froze. =( is this the end of my iphone? Could this still be repaired or am i better off just getting a new phone? Coz i mean, if i end up having this repaired and end up paying 150-200 bucks, i might just get an upgrade for 200 bucks which is more logical.

Are there any attractive and protective iPhone 4s cases?

I currently have an Otterbox but its bland and doesn't display my personality. There are other cases that are more my style but I feel like if I drop my phone in one of those cases I'll be shelling out hundreds of dollars for a new phone. So is there something I can do to make my phone more durable in a stylish case, or a case that is stylish that offers protection?

Why can't I sign any players in FIFA 12?

I just finished a season in manager mode, and i didn't renew all of my players contracts, but I still had 11 players. So I played 1 game into the next season and when I went to play my second it said I didn't have 11 and I need to sign someone. However it won't let me sign anyone from any league since its not the transfer season. I don't know how to sign any players I've scouted, and there are no free agents available. It won't let me play any more matches unless I forfeit. So what can I do? I wouldn't mind forfeiting a couple matches if the transfer season is soon, I'm only 1 week in. Any Ideas? I'm on the iPhone as well
