Why does my iphone keep kicking me off Wi-Fi?

I just got a brand new iphone 4 yesterday and it keeps kicking me off Wi-Fi for a few seconds or longer (it goes back to displaying the 3G) and then automatically connects me back. Every once in awhile I have to go in and manually select my Wi-Fi for it to connect again. The problem isn't the Wi-Fi as my fiances iphone 4 is working fine.
We installed ios6 onto it as soon as I got it and my fiance thinks that may have something to do with it since his does not have it.
Also, we tried resetting the router, my iphone and switching the Wi-Fi on my phone on and off but nothing helps.

Anyone out there know the solution? I don't want to run up my data costs.

Keep iPhone 4 until it dies down or upgrade to the 5?

I've had an upgrade since May on my iPhone 4, so it's been a bit over two years since I've had the phone. Should I take my upgrade? (I've already pre-ordered it, so, yes, I can return it).Is three to four years too long to keep a phone? This is the longest I've ever had a phone. All my other phones I've only had for a year.

What happens if my iPhone 5 was stolen?

I just bought the iPhone 5 today and while I was on the bus, it was stolen. Will Verizon be able to track it? What would be my fees? I barely used it. Would verizon be able to replace it?

Did rice fix your iPhone after water damage?

Dropped my iPhone 4S in the toilet last night. It was only in there for a split second - I grabbed it immediately and wrapped it in a towel. I rushed out and bought some rice and put the phone in a ziploc bag full of it. I can't see any water in the camera lens or anything, and only the headphone jack damage indicator is red (the charging dock one is still white). How long should I leave it in there? What are its chances of survival?
