 Run redsn0w, click browse and pick the iPhone2,1... file.

 I'll text you with your bootrom version when you tell me the serial, when you get asked what bootrom you have, if I say new click yes, old: no.

Click next through the rest of the thing and then follow the instructions to put it in DFU mode, then it will do the rest and activate and such.
