Do you mean having to 'Boot tethered' every time you restart?

Or are you literally stuck at the activating screen?

Good for you!

GoldMan, are you trying to activate the phone or just trying to jailbreak? Also, what operating system is the computer running that you are hooking your phone to?

Here's what I've learned. If you are running Windows 7, you need to run redsn0w in Windows XP compatible mode. I honestly can't tell you how to do that since I use XP. Also, there is a Windows version of redsn0w. Also, I think that the current redsn0w only jailbreaks 4.2.1. Once RS does it's first "jailbreak", you have to jailbreak again right after that. I'm sure you have read instructions on the steps. Don't forget that when jailbreaking with RS, it does take a few minutes for the iDevice to finish receiving the files. If you have more questions, we're here to help.

What model of phone, baseband version, and (if 3GS) bootrom version do you have?

I still don't know what my own bootrom is.
