How to restore my iPhone without iTunes?

I have an iPhone 4 running 4.2.8, and i jailbroke it awhile ago, although i deleted cydia. I want to update my iphone, but it won't let me with the jailbroken content on my phone. So i tried to restore it, but whenever I try with itunes i always run into error 3194. I've tried to fix this by modifying my host file and using tiny umbrella to unsave the shsh caches from Cydia, but neither of them worked to get rid of error 3194. I have also tried using dfu and resetting from the phone, but as you can guess they didn't work either. I'm wondering if there's any software that I can download that will just restore my phone for me, so that i can get rid of the jailbroken content for good. Please help me! I can hardly get any new apps because they all require the updates. My phone has been stuck like this for a good 6 months!

Will at&t give me a new sim card?

Okay so I have a windows phone for at&t and I have a date plan and everything. I want to buy an iPhone off of eBay but if I do my sim card is too big for the iPhone 4 since it requires a micro sim card and I have a regular one. I don't want to risk cutting it and breaking it, what I want to know is that if I do buy the phone and go to my local at&t store will they supply the micro sim card that I need for the iPhone I bought from eBay because my regular sim card won't fit into the iPhone 4?

What is an apple fanboy? Am i one?

What exactly is an apple fanboy? I've owned four smartphones so far. All android powered. An htc eris. An htc incredible. A htc thunderbolt. And my current phone. The motorola droid razr. The razr is my favorite by far. I'm pretty tech savy and know how to root my phone and other devices. So android is good for me since it has alot of options. Anyway. I recently decided i want a new phone. Something different. A new expirience. I looked at the galaxy s3 and the iphone 5. I know they are both good phones. The galaxy being a bit more of a beast right out of the box. But i chose the iphone for the new expirience. Iv owned ipods and an ipad. I absolutly love their stuff. I have never even used an iphone before. But i like apple. I know they restrict their options but i can root it or jailbreak and unlock its potential. I don't know of anything i can't do with the iphone that i can with my droid. Same apps. Widgits of sorts. It does what i need. I'm happy with my choice. I played with the iphone alot and i love its simplicity. And the way its built. I wasn't a fan of the glass on the previous models but the new aluminum back is nice. I like it better than the kevlar on my droid. Feels nicer to me.

Does this make me an apple fanboy?
What's your opinion on the choice i made?

IPhone charger is literally de-charging my phone?

I just bought a new iPhone charger (not an Apple product. First mistake) and it's literally taking battery life away lol. I plugged my phone in at 12% and it's going down…
I can return it, not a problem.
I'm just wondering if this can be fixed. If not, anyone have a clue as to why that would be? I'm curious now lol

Added (1). It's a wall-charger. It charges fine with my computer. Very strange! I've even tried switching out the USB chord for another one to see if that was the problem--it's not.
So I guess the phone's battery is fine?

How easy does an iphone 4s break?

Everyone keeps saying that i need to have an otter box on it at all times. I don't like otter boxes so i was wandering if you have a different type of case on it will it still break as easily as it can without it.
