How to track how much I use my iPhone?

My wife and I disagree about who uses their iPhone more. Is there an app that will track (not the data used or minutes used) but how much the iPhone is on, clicked or used I any given period?

Why does my Facebook photo upload fail every time on my iPhone 5?

I recently got an iPhone 5 and this morning I tried to upload four photos to Facebook from my camera roll, but the progress bar would quickly reach 25% and then say "upload failed." I have enabled location services from Facebook (others' solution to this same problem) and it didn't work. How do I successfully upload photos?

How to access the photos in my old iPhone backup (on a PC)?

Wife and I upgraded our iPhone 3GS to the 4S. I use a Mac… She uses a Win7 laptop. Before going to the store, I backed up her iPhone to her computer. I don't know Win7 very well… So I need your help! We no longer have her old 3GS but she wants her old iPhone photos. How do I get them out of the backup? Nobody seems to have the answer no matter how much I Google and dig in the catacombs of windows directories. Gah! Why can't the whole world be perfect like a Mac? SMH

Buying an iPhone off of Craigslist?

My mom and I want to each buy an iPhone off of Craigslist. We want to do this because we don't need data anywhere and we can't afford that. We will just use Wi-Fi when we have it. We were planning on buying them locally in our area to be able to see the phones before we buy. Is this okay? Can we switch our numbers to the iPhone without paying for data?

Can I use my home Wi-Fi on an iphone?

If I get an iphone used from Gamestop and put my AT&T sim card in, can I use my home Wi-Fi instead of getting a data plan? Thanks! (And I know I wouldn't be able to get Wi-Fi anywhere else, I'm okay with that.)
