Computer will not recognize iPhone 3G

My iPhone 3G can be charged through an outlet, but all computers will not recognize it (This includes iTunes) It was recently damaged on the inside; the pins were messed up. My father fixed it maually so that it could be charged again; however, I can't get it to connect to ANY computer. I've tried 2 different computers, reinstalling iTunes, and using 2 different USB cables, but nothing works!

Please note that it isn't the cables that are the problem; both cables work fine on my iPod nano chromatic.

Do I have OCD or am I just a neat freak?

Let's see… I always have to clear my calculator before doing another math problem, I hate when things are not in place for example, if there's a dot on something when it shouldn't be there or a picture is crooked or when I write an essay and the words are not in a straight line I get crazy.
I have an iPhone 4 and it MUST BE 4x4! They must have four rows and columns or I have weird anxiety or something, also the springboard or the black room when you double click the home button must either have less or equal to 4 apps. If I have one app in one page I just stare at it and calculate which app I can delete or merge together.
I also have problems with numbers, if my photo gallery is in the 0s like 100s, 200s, 300s etc I get a little nervous but if its 499, 498 or 497 I get really mad. Less than 50s are my ideal numbers.
Also, there must be certain pillows on my bed and if I don't like it, I sleep on the floor with two.

Added (1). Also the red notification drives me mad, I must always make sure my mail notification is 0 an my App Store must be 0

Does a GPS application on an Iphone eat into my data plan?

I want to get an Iphone 4s but AT&T's data plans are a bit expensive. I have wi-fi at home and would probably rarely use anything more than 300 MB but I'm worried if I have to use the phone for GPS that it will eat into my data and use all of it or more up. So do GPS apps actually use your data? If not, how exactly do they work?

How to download an update from my iPhone 4S?

I just got an update on my iPhone, but it won't let me download it. It says it needs a Wi-Fi connection to download. I don't get it. I already have a Wi-Fi connection to the iPhone.

How much does the iphone 4 cost for At&t?

The IPhone 5 has come out, I have an available upgrade. How much would it be to just drop by the mall and get an Iphone 4? (not 4s.)

Added (1). Thanks. I knew it was something really low, I just didn't know if there was a catch.

Updating an Unlocked Jailbroken iPhone 3Gs to IOS6?

A bit complicated. I recently bought an unlocked jailbroken iPhone on eBay from a fairly credible source. It's 3Gs version 5.1.1 or something of that nature. Press me for more details if needed.

But the question is, I want to update it to IOS6. Now I know it has to be jailbroken, so if I de-jailbreak it or whatever and update it, will I lose the unlockability? Thanks in advance

Added (1). In response to the first person, I don't care to jailbreak it again. I never use it. But, is it possible to update it anyway?
