IPhone 3gs keeps restarting to apple logo?

The other day my iPhone restarted itself to the apple logo while i was in the middle of texting one of my friends. I didn't think much of it and continued playing on it. Later it did it again while i was playing on it. It has happened another 2 or 3 times since then. I have not broken my iphone or dropped it in water or anything it just started doing this the other day out of the blue. If anyone knows what is wrong with it or how to fix it please tell me. Also i do not have warranty so i can't take it to the apple store and my mom will not buy me another one any time soon.

Is FreeMyApps safe and reliable to use?

I have an iPhone as well as an iPad, and there are lots of great apps out there which I'd like to get, but I just don't want to spend so much money to buy all of them. So I was looking up ways to get these apps for free, and this was one of the ways that had popped up. I'd researched into it a little, gone to their facebook page, looked up reviews, and so on, but I don't know if its safe to use. Everyone seems to have mixed feelings about it, either loving it, or doubting it's security. Would it damage my devices or hack into it in any way? I wouldn't want to wreck my apple products to get 5 dollars worth of apps for free.
And another thing that's rather critical, does it work I'm from Canada? Is it US app store only?

Cutting sim card to fit iphone 4?

My contract ran out on my iphone 4 so i got an iphone 5, i want to give my iphone 4 to my dad but he has one of those big sim cards. Is it possible to cut it/where can i get it cut to fit the iphone 4? I rang t-mobile and they said 9/10 times it won't work.

The only reason for the cutting is so my dad can keep his old number instead of t-mobile giving him a new sim. Also can't tmobile give me a new nano sim with my dads old number on?
