I haven't announced my issues with the G1 hardware I've had, primarily because they've been due to my stupidity, but, of late, I've had to hard reset my Android phone a few times in the last year or so. It always takes me a while to figure out what I had on there and then go through the painful addition of those apps. So here's a list:
Amazon Mobile
Google Finance
CompareEverywhere
Shop savvy
Twidgit Lite
Google Sky Map
Astrid
Last.fm
Shazam
Layar
ConnectBot - ssh
Movies by Flixter
PicSay
Google Voice
Weather forecast widget v2, Francois DESLANDES
Digital Clock Widget, Maize
FBReaderJ - an epub reader
