Having problem restoring jailbroken iPhone 4s?

I decided I want to remove the jailbreak from my phone. I first deleted all of the cydia files/ addons on the phone and backed it up. I put the phone in DHU mode, ran TinyUmbrella, and tried to restore to a IPSW version of 5.1.1 (the version my phone was when I first jailbroke it). I want to update my phone to iOS 6 and not have the jailbreak on, but keep on getting 11/1600 errors. Could someone please help, I'm freaking out and don't want my phone to turn into a paperweight. If you need any extra info, please message me. I'd be very grateful if any of you could help me.

Instagram doesn't work with iPhone 3G?

My iPhone is IOS 4.2.1. When I try to download it, it says that I need IOS 4.3.
Is there a way I can get a past version that works with my phone or something?
Thanks.

Added (1). I can't update it since the iPhone 3G only goes to IOS 4.2.1.

Just switched my number to a new iphone, but my old phone still works?

I just went and started an individual plan and got a new iphone 5, and they carried over my number from the virgin mobile prepaid i had before. My new iphone can make calls and send and receive texts… But so can my old phone. And when i called my cell number using my house phone, my old phone rang, but my new iphone didn't. Do i have to like cancel service or something? I'm confused about what to do, the guys at apple didn't mention anything about it.

What should I do with my Apple iPhone 3GS?

My new iPhone 5 is (finally) going to be delivered within the next couple days and I'll no longer be a slave to my cracked screen and slow running iPhone 3GS. I know I could sell it, but I'll only score something like $30 for it, I could just keep it around for a backup iPod Touch (and phone if something happens to the 5), but that seems like a waste of all this technology. There's got to be something cool I can do with an iPhone 3GS now that it will no longer be used primarily as its intended purpose. So what kind of cool stuff can I find to do with my old iPhone, people? Link me up with something really cool…

Does downloading apps on iPhone take a lot of data?

My internet plan is 8gb for four weeks and it only lasted a week or so. Usually is does not go this quickly. My room mate has recently got an iPhone and has started to download and use a lot of applications.

Do you think this is due to downloading and using apps? I have little knowledge on data usage ect
