iPhone touch screen not working

I have a unlocked 1.1.2 iPhone that stopped responding to touch an hour ago.
I got a tmobile pay as you go sim card about a week ago, and everything has been working good with that. I didn't drop it or anything like that to make it stop working.

I know that it sometimes stops responding to touch, I sleep it and slide to unlock and it works again.

What I need to know is if there is anything I can do right now to get it working again? If not, I need to back up my notes over ssh if possible, then restore to 1.1.2. (and if that dosen't fix it, I know its bad.)

Thanks for suggestions in advance!

Can I just get the 1.1.2 firmware and restore it?

Do I need to get the 1.1.1, jailbreakme, octoprep, then upgrade to 1.1.2?

I haven't done this in a while, so any tips would be appreciated...

I dont have 60 dollars a month...

I only put down $10 for the sim card and put 30 minutes on it. It works for me.

Ill try restoring to 1.1.1 now then.

I just restored it to 1.1.1, ran iNdependence once, and now Im at the Activate iPhone screen, ready to jailbreakme.com.

Problem is, I cant slide for emergency. The touch still doesn't work...

Now what do I do? Should I call Apple? Take it into the store?

I can say it stopped working, so I restored it, and now it still doesn't work, and this is where I am now...

I took it to the Apple store, and they said I need to have an active AT&T account for service on it.

I don't have my sim card (I lost it, dammit) so I need to get a replacement sim from the AT&T store, register in itunes, take it to the Apple store for service, get a fixed phone, cancel the AT&T plan, jailbreak and unlock new phone...

Still waiting on going to get a replacement sim card.

I am 16 years old, and don't need a phone unless I am driving or at college. Basically for emergencies, and 10 cent texts to whoever I need to communicate with.

We do have a family phone that my brothers and I share, and thats what I've been using. With 20 dollars to get a pay as you go card, it will last me a few months and then I can pay 10 dollars again. (then I don't have to carry a cell phone and an iPod with me).

I would rather save 2 years (Total of $1440), use my iPhone, and get something like a new MBP.

Sorry about going off topic, but Im still saving up $25 for that replacement sim card though.

The whole shenanigan cost me $0.00.

I went to the AT&T store, and the guy gave me a sim card (punch out credit card type thing) for free, I registered it sitting at the genius bar, handed him my broken (and now registered with phone number phone), and I got a shiney new refurb iPhone! I just called AT&T, and canceled for free (within the first 3 days).


So, now I have a factory activated 1.1.3 iPhone. How do I go about unlocking and getting installer.app on there the easiest way?

Does anyone recommend waiting for the SDK update so I can go into it with a virgin iPhone?

Thanks!

Edit: already trying this out - http://modmyifone.com/wiki/index.php/Unlock_Activate_Jailbreak_113_iPhone

Double Edit: Ok, its activated and jailbroken with installer.app, now I don't know what booloader it has (I cant find hw info in installer)

I have a week 05 iPhone (apparently), but Im not sure because its a refurb... Is there any easy ways to tell?


Tripeley Edit: It works! I now have an unlocked 1.1.3 shiney new iPhone! Thanks for all the help everyone!
