For past 2,3 years I have been using PDAXRom 1.1 Beta2 on my lovely Tosa. It does everything I need it to do: play mp3 and avi, light browsing, abiword, dictionary, and viewing pdf.
I was so afraid to broke my perfectly tweaked ROM and I stopped doing any update at all. After all those time, I finally decided to move on and started experimenting again.
I guess I will give Angsrom a try and see what happens!!
