I've published a couple of apps now...
Easiest is to get them from market I guess... https://market.android.com/developer?pub=MuMu21
My first test-app.
Shows a new picture every day from http://hest.se (chooses among the highest rated pictures)
Shows a log of boot times and up times.
Market is good, but could be way better, like searching the way we (I) want.
