Help! I really need help!!

[joepic]

guys, I've been looking all over the internet this morning for some desperate help. I tried so much and failed. I came here and it seems like you guys could help me.
Here's my problem:

My iPhone was at 1.1.1, unlocked with t-mobile. It was fine, for about 2 months.


Today, I took the risk to upgrade it to 1.1.3. It worked. Perfectly using the new ibrickr.

Well, I decided to go into the installer app, and uninstall all my old apps. They weren't showing up, but they still appeared on the installer app. After uninstalling them all, I hit the home button and it was loading forever. So I restarted it, and the Apple logo only appeared. It would not start up. Only the apple logo would show...

So I made a stupid mistake - I downgraded to 1.1.1.

After realizing this was a bad move, I'm trying to downgrade that to 1.0.2. I think I was successful, following this

Well, Apptap won't jailbreak it for me and install the installer app.

Is there another method? Is there something I missed?

I need to jailbreak 1.0.2. I'm stuck at the activation screen.

Thanks guys please help!!
