I need to delete 15,000 photos from my iPhone 5?

I have ios7 on an original iPhone 5. I have access to a MacBook. I need a pretty much one step option to delete all 15,000 photos from my phone since I already have them all saved to my computer, and the options I've found such as selecting them by date will take me around 600+ taps on the iPhone itself and I'm not selecting them all individually since there are 15,000 photos any ideas are appreciated

Dropped iphone 5, speakers are crackly?

I just dropped my iphone 5 in the snow. When I tried to play music out of the speaker, some message popped up (which I didn't read), and the sound came out really crackly, and it wasn't as loud as it usually was. Also, I noticed that i can't muffle the sound by covering the right set of speaker grills, which I usually can. What's wrong with it and how can I fix it?

How much would it cost to upgrade to an iPhone on sprint?

Currently, i'm on a family plan on sprint. I have a regular texting phone with no data. There are a few other lines on this plan that have the unlimited data with smart phones. (I'm the only one without a smart phone). I wanted to know how much it would cost to upgrade to data with the iPhone 5c? On the website it costs 0$ for the phone if you start a new plan. Since i'm not on a data plan already, i assume this applies for me. Am i right?
