imei change tutorial for sonyericsson

I had an IMEI change as well and i updated to 2.1 and attempted to jailbreak it through QuickPwn, which was a failure, trying to get that fixed now. But anyways it had reset my IMEI back to the iPhone. It sucks, after i get my 2.1 running i probably will not be able to use SwirlyMMS. And currently there are no programs to change your imei right now. And you cannot use ZiPhone to do it again ...
