Dropped iphone 4 in hot tub?

2 days ago at night i dropped my phone into the hottub. I quickly grapped it out but didn't turn it off. It turned off on its own like the screen just automatically turned black after about 30 seconds of grabbing it out. Anyways, i took the case off and its been sitting in this quinoa kinda rice stuff. Its only been about 34 hours since i've dropped it and 3-4 times since its been in the rice i've tried plugging it in and turning it on. Nothing happens. But just now i tried and i noticed the back sort of popped open. On the upper right side you can almost see inside the phone. My dad thinks its because the wires are so fried.
Do you think its going to turn on?
Although i'm eligible to get a new phone, i really need this one to turn on because i have really important contacts and photos. I never backed my phone into i cloud. So also is there anyway i can get that retrieved bygoing somewhere to get it fixed?

It pops open because of the battery. The chemicals in it react to water and expand. You probably have a new paperweight but first see if you can get a repalcement battery, find out how to replace it via a video on youtube (brilliant how-to videos on there for most phones) and then see if it'll come on. Likely too that you're stuff is on the micro SD card which you can get 'read' by anyone with a card reader. Otherwise, new phone and lost data.

Bottom line, the phone has to have some power source to remove anything from it. Since you've never synced with iTunes or iCloud odds are your information is gone as iPhones don't have SD memory. It's all internal. If it will power at all, then try to sync to iTunes or something. Otherwise, sounds like it's a lost cause but it could take weeks to power on. Best luck.
