How long does it take an iphone 3 to die completely?

Heres the story, I downloaded this app called cocoppa (stay away!) and it made my phone get this white screen. I try to shut it down but nothing happens. I suppose my only hope is to let it die. Unfortunately, I had charged my phone to a whopping 100% before this operation took place, so my question is, how long do i have to suffer being phoneless before my phone completely dies? The screen doesn't go dark at all, so i assume it shouldn't be that long as it uses more energy being bright.

How to activate my iPhone 4s? - 2

I bought an iPhone 4s off of kijiji and I can't activate it as it is locked to a different carrier. (it is locked to AT&T and I would like to use it with Fido. When I put my sim card in the phone it takes a long time to load and then tells me to connect to iTunes. When I connect to iTunes it loads for a while as well and then says: " We're sorry, we're unable to continue with your activation at this time." I'm assuming this is because my phone is locked to AT&Tand i'm trying to activate using a Fido sim card. However, how do I get into the phone to unlock it? I have also paid $6.95 to request an unlock code and am waiting for it but I'm not sure how i'm going to use it if i can't get into the phone to enter it. Help!

Added (1). @AVDADDY: Yes, you would think I'd have thought of that before ; but not knowing much about Iphones I assumed that when I bought it I would be able to unlock it by using a simple online software or by taking it in… After going through all of this it looks like all of the phones that are being unlocked have already gotten past the activation stage, i can't get past it.

What should I do to get Internet access overseas?

During the summer I will be going overseas from the us to Croatia. However, I will possibly be taking an online course and need Internet connection over the entire course. The place where I will be staying at has an computer with Internet access, however the computer might as well be an dinosaur with Internet speeds of a snail. I'm planning to bring my Ipad and iPhone to do the curse, however I'm stuck with the dilemma of getting Internet access while in Croatia on my iPad and iPhone.
PS: the computer has a router but it is not wireless, and money is of no issue.
Anybody have a solution?

Will syncing my iPhone erase all of my data?

My computer had a hard drive problem so they replaced my computer. I know syncing my iPhone (4s if it matters) to the computer will wipe the current music on my phone, which is fine. I just want to know if it will wipe my other data. Such as pictures, apps, things like that. I would just like to know if it does or not before I sync just so I can save my pictures and things to another place.
