My mobile data service isn't working?

I have an iPhone 4s. I was experiencing an overheating problem with my iPhone and I read somewhere online that if you reset your network settings then it fixes the problem so that's what I did.

IPhone 3GS Dies at 80% Battery then turns on after 15 Minutes

My iPhone 3GS would be at full charge 100% then after just unlocking it and using it for just 1 minute it drops to 80%. Then when I use the camera a lot or just browsing through the App Store it just shuts off. When I try to turn the device back on it shows me the battery indicator (showing that I need to charge the phone), even though It was at 80% when I shut off. So I turn on the phone again with the power button and it still gives me the sign, and after a few tries or 15 minutes later when I press the power button it turns on and works properly but it might shut off again if I use the Phone, Camera, or App Store.

How to restore my jailbroken iPhone 3G?

So basically I have an iPhone 3G that was running 4.2.1 and unlocked with ultrasnow by upgrading to the iPad baseband. My friend used my phone and 'erased all content and settings' in the settings and of course now it doesn't boot. I've tried restoring it (only to get error 1015 at the end), re-jailbreaking it only for it to hang on the pwning screen and I've also tried using iREB to install custom firmware through iTunes but iTunes brings up error 21 and cancels it. I then tried with another version of iREB and got error 1600. Does anyone know how I can restore my iPhone? Help would be greatly appreciated. Thanks in advance.

Added (1). I've already tried the shift-click restore several times. I get the same error
