Opinions on what I should do to better protect my iphone 4?

My old phone drowned in my hands at a music festival last year and I'm going again July 5th, coming up quickly and I really need to protect it this year

(If you watch the show "Warped Roadies" the episode where they go to Toronto and the giant rain storm happened, that's where my phone drowned)

On Saturday I'm going to go pick up a knock off Otterbox case for the phone, but that only helps me with dropping… I'm worried about rain 'cause you never know.

I was looking at this:

But I think that is a bit expensive… Opinions?

Pretty much all… I can't afford much due to my age and lack of money.

Thanks!

Added (1). Nobody in my house can afford an otterbox case, however my dad's girlfriend bought a knock off that is the exact same thing except it doesn't have the otterbox logo on it

The product you linked in your question is not intended for more than two uses per skin which is not good, once your done with the skins you have buy more, I would go with the Otterbox. For you not to get a fake Otterbox, i would recommend buying one from otterbox.com or any store which sells them like Best Buy.

I agree you should get an Otterbox I use one on my phone at work and it has saved me more times then I would like to count
