How to recover deleted pics from an iPhone?

Greetings!

Two weeks ago i took some photos of a weding. Few days after that I decided to clean up my phone memory by deleting few pictures, so i accidently deleted some of those wedding pics.

My phone was backuped like 2 months ago, I didn't have my phone pluged in a computer + i didn't use iCloud.

Is there a way I could recover those pics?

IPhone 4s battery dying in 2 hours?

Well I've had my iPhone for almost one year now and my battery is dying much quicker than it should be. I took my phone off the charger this morning (100% full) and went for a two hour run. I had music playing, but still, two hours is not right.So, what could be causing this? Oh and I'm running IOS 5.1 if that makes any difference.

At my school are way to materialistic

So I'm going to be a sophomore in high school. The thing is most girls at my school are snotty kids who get everything they want. This one girl in my class had an iPhone 3GS and was hardcore complaining to her friend like "UGH I really need an iPhone 4! Mine is So outdated! My mom is crazy for not letting me get one I mean, I NEED an update!" and then the next day she comes in with a freaking iPhone 4s. Wth. They're always complaining about their shoes, phone, and their "boyfriend drama". I can't stand it! Please tell me I'm not the only one!
