How Do I Activate iPhone 4 Without AT&T SIM?

I was trying to jailbreak and restored it by accident. I don't have an at&t micro sim, not even a sim. All I have is my T-Mobile SIM which I cut down to micro size. Version is 4.3.5, how can I activate it? I'm utterly mad and annoyed right now.

It can't be activated unless you put in a SIM card (it doesn't have to be an active SIM card).

Does it have to be an AT&T SIM?

No, I activated mine with an inactive T-MO sim I cut down to micro size.

Well, sure didn't work for me. Screw it, I bought a factory unlocked iPhone 4 on Amazon and a T-Mobile micro SIM. I've been through two eBay "Unlocked" iPhones and neither have turned out good. First one was all scratched, dented, damaged and the one I have right now came with the Gevey bullsh... and I couldn't even activate the phone. I think I should have bought a factory unlocked at first but I confused unlocked with such term.
