How long should i let my iphone sit in rice?

I dropped my iphone in the toilet for about 4 seconds, turned it on, it didn't work. So i held down the home button and the power button for a long time and the apple just stayed on there a flickered a bit, and an hour after sitting in rice it didn't turn on at all (I know i was stupid for turning it on, but at the time i was at my friends house and my parents needed to call me)

I didn't take the battery out either ( i didn't have the right tools.) So its been in rice all evening now.

I dropped my iphone in the toilet - 3

I have an iphone 4 and i had it in my pocket and i pulled my pants down and it fell out into the toilet. It was there for like 3 seconds and i put it in rice as soon as i took it out and I've had it in rice all night, how long will it take to dry out and be able to be used again?

Certain Videos not playing right?

When I transfer videos from my iphone to my computer (not streaming video), the videos that were taken on my iphone 3gs play just fine. I got the new 4S a few months ago and the videos that I transfer from that will not play right. By that, I mean that the audio plays normal, but the video does not keep up with the audio. By the end of a 2 minute video, the visual part will still be behind 15 seconds or so. The same with videos transferred from my GoPro Hero 3 camera. Older videos taken on my 3gs still play just fine, but newer videos do what I described above. I have already updated to the latest graphics drivers, windows updates, etc, and nothing has fixed this issue. I have a gateway with Vista 64 bit, AMD dual core 2.1ghz ATI 3000 HD series graphics, 3gb ram, and 500gb HDD. I have tried using different formats (i.e.quicktime player, WMP, etc) and they all do the exact same thing. Any ideas?

Messed up iPhone 5 activation?

Ok, so my friend got her iPhone 5, and we were setting it up, when we finished, the phone won't send messages and her old phone is still getting her calls and texts. We didn't turn the old phone OFF when we activated the new phone. So now the new one, doesn't have service and it doesn't get messages, make calls, etc. How do you re-activate it? Or can we COMPLETELY start the WHOLE thing over as if it was brand new out of the box, and we set up language, country, find my iPhone, again,?
