iPhone Unlock/Jailbreak Help for new 3.0 firmware!?

i hope you read all of this... Ok first off, I have a 8gig 2G iPhone(the old one), T-Mobile is my carrier, i have jailbroken older versions of firmware(1.1.4, 2.2, 2.2.1), im running this on Vista, (thats all i have), im using Quickpwn 3.0 Beta 3,and im desperate. You Should Know... I Had Jailbroken and unlocked The 3.0 firmware on my phone once before, but then i downloaded poof from icy and accidentally hid icy AND poof, so then i wanted to re-jailbreak my iphone to see if i could get icy back to normal but then this... every time i try to "Shift+Restore" to choose a firmware, when i choose it, and it starts to extract the firmware and stuff, it just stops and an error window pops up that says "could not restore blah blah error 1600 Blah Blah!" I dont know what to do! And Yes i put the phone in recovery mode before i do any of the above^^ I have Tried... - Using quickpwn without restoring - using a different .ipsw And different Quickpwn beta's(1,2,4,&5) - restarting computer - restarting phone - taking my sim card out - Google-ing my problem - using all my different usb ports - and ive tried relaxing and taking it slow but nothing seems to work!
