[1st Gen] can i get Kindle Launcher on ICS?

Short answer is that no, the stock setup where you swipe through books is not available on ICS or JB. I think the Kindle app is pretty much just as good on ICS and JB. Certainly does everything I need it to. If it's scaled back at all, it's certainly nothing I miss. I didn't even use the KF that much with the stock software. You can still change background, spacing, font sizes, brightness etc, so it's pretty much full featured. You just can't swipe through books like you can with the stock setup. You gain far more than you lose.

If you're interested, there is a rom (Modaco?) that has the stock KF launcher with Google Play capabilities built on, so you can kind of have the best of both worlds, but again, that's for GB only.

 

IMHO once you flash JB or ICS onto your kindle, you'll never want to go back to the stock kindle launcher. Admittedly, the setup is great for books, but that's about the only thing I liked about it.
