How do I run a Google Calendar app on B&N Nook Simple Touch? How do I run a Google Calendar app on B&amp;N Nook Simple Touch?

I never had a Nook, but I'm interested in buying it to use as a dedicated e-ink wall calendar; I heard it can run Google Calendar; if it indeed does, then all I need is to run it once and leave it alone, given the screensaver is disabled. Making it autorun on startup would be even better.

I have asked about disabling the screensaver elsewhere.
Root it by flashing one of images available on the net. Lifehacker has simewhat old instructions which worked for me. GCal runs fine it seems, but I have pretty annoying graphical glitch which I'm sure is solvable. I used NookManager image IIRC
