Hi everyone. I've been playing guitar for about a year now, but I've been writing software for over 20 and I've written some software to help my guitar study. It's available now for T-Mobile G1 (android) phones.
Chordtronic has detailed fingering of nearly 1600 chords (open, basic, barre, obscure, lots!).
You can get more info about the application here:

You can buy it now for $1.99 in the G1 Market application in the Application > Reference section.
Thanks,
