Stuck at activation on iphone with unknown original service provider,

Ok here goes nothing. I have a 3 G iphone, that when I bought it I got it used, and basically got ****** over by doing so. It turns out that the phone was locked to an unknown service provider. So I went out and bought another one, and have had this one sitting here for months waiting for yellowsn0w to come out. So now I start reading all the Walkthrough saying that the baseband has to be 02.28.00 freshly updated 2.2. So without thinking I downloaded the firmware and connected the phone but after I flashed the phone I didn’t have any way to activate the phone through ITunes. If someone can help me with getting this phone activated I should be able to get it jail broken and ultimately UNLOCKED and functional.

Thank You For Your Time Wilson
