How to develop iphone apps on Windows 7?

I would like to develop iphone apps on Windows 7 using objective C. I know the final procedure will still require an apple product to upload the app to the apple market. But I would like to know if there's any IDEs for development using objective C in windows 7 besides installing Mac OS on pc or a mac os vmware?

Can I charge two iPhones using a car charger with two ports?

We have a car charger that charges iPhones before the iPhone 5 (like my mom's 4S). The charger also has a usb port so you can plug in something else. In this case, we're trying to plug in the USB cord to charge my dad's iPhone 5 while also charging the 4S. Is this possible? Can we charge both? Will it make everything explode?

I think water leaked through my iPhone's life proof case?

I just bought a new life proof case from best buy. I took it home to use it in the pool. I tested the case first to make sure no water got in without the phone, none did. Then I put in my phone. I used it in the pool for about 10 minutes. I realized there was some water inside it (just on the screen) so I quickly took it off and wiped the screen down. I let it sit. And took only the case in the pool. It seemed to have no leaks in it. So I put my phone back in. I used it for about 15 minutes, then I tried playing music under water it worked. When I went inside the phone was making a staticky noise. I turned on the music and it worked fine. I then turned off the phone and the noise stopped. Now it is sitting in a bag of rice.

Final questions:
Is my phone broken?
If not how long does it have to sit in the rice?
If it is, does life proof cover my phone breaking in the pool?

Added (1). I have an iPhone 4S.
And I know the life proof does something about a one year warranty. Does that only get you another case? Or a new phone as well?

Can I use my Elevate Hotspot as a Wireless Network?

I have an Elevate Hotspot from AT&T that we use for our internet in the house. We live way out in the country and that's all we have available. I want to buy a Wi-Fi enabled printer so that I can airprint from our iphones and ipad.Am I able to connect the printer to the hotspot and print from our iOS devices, or do I need to purchase a router?
