Experience with lifeproof case?

I have the iPhone 5 and want the lifeproof case for taking in the water but there are some pretty bad reviews on it saying that it is not watertight and ruins your iphone. Should I buy it? Who's had a good or bad experience with it? My other choice would be the mophie juice pack helium because its like having an extra battery for your phone. What do you recommend? I already have an otterbox defender, incipio dualpro, black bumper with clear back case, and 2 silicon skins.

IPhone sync into another computer?

So recently my laptop sadly gave up and died the other day. I've had it for so long and that was the laptop that I use to put all my music, apps, photos etc. And today I wanted to put some new music into my iPhone but I can't because the laptop that I use to sync my iPhone into has broken and now I have my big computer which I use for gaming, is all that's left to sync it with. If I sync my iPhone over to the big computer will all my music, photos, data and everything be deleted?

So is there a way to transfer the data from my iPhone to the big computer without having to delete it and download it all over again?

How to get iMessages on iPhone 3GS?

Yeah, I know this part: settings>messages>turn on iMessages and I can receive iMessages from certain people when they send it to me FIRST.

My first question is, how do I send an iMessages message without the person sending it first. My second question is, is there an app for iMessages. Like on the iPhone 4, there's a separate app for iMessages rather than it being combined to messages. If so, how?

How to contact Apple Support for forgotten pass code on iPhone 5?

So all my friends saw me type in my passcode on my iphone 5 so I changed it.
However, I'm an idiot and I forgot it.
