That's what I got to thinking, Hboot 1.58 is needed to run the 2.89 ruu isn't it?

Nope!! You can run the 2.89 RUU which will update you to hboot 1.58. You just can't go backward unless you are s-off. So if you do it, you'll be stuck with 1.58 until you are s-off.

when I was restoring my Common Sense NANDroid (from 1.5), but everything worked out just peachy, and have no problems. I just had it stuck in my head to go to 2.89 since I'm not quite ready for JB just yet. And I actually LIKE Sense, and there seems to be more ICS Sense ROMs to play with than JB! 
), for him to stay on 1.5!
