How old should a child be to have an iPhone?

My 11 year old has been begging for an iPhone 4S because all of her friends have iPhones. All of her friends have iPhone 5Cs and all sorts! Should I get her one? How old should she be?

What's a good camera that records high quality video and takes awesome pictures?

I'm going on a trip to the Niagara Falls and my dad asked me to look for a good camera since the one we have is 5 years old and takes very bad pictures. My iPhone takes better pictures than that camera. What's a good camera that both records high quality videos and takes awesome pictures. I don't want a big DSLR camera though, just a small compact camera that I can put in my pocket.

Should I purchase the IPhone 5s now or wait till the IPhone 6?

I'm planning to pay out for a phone contract, however I'm not sure whether to buy the 5s or just wait for the IPhone 6. I have looked on websites saying it maybe be release sometime in September or October 2014; some time around there. I would just like to know other peoples opinions on this matter.
