HP iPAQ rw6828 ROM Update
HP have released firmware update 1.01.03 for the rw6828.
I'll be interested to see if this fixed the annoying "feature" where the wireless card spontaneously turns itself on - a great way to shorten the battery life.
Update: This update refuses to install via my Vista machine. I'll try it at home on the WinXP box to see if it is happier. I had a small panic until I read the readme.txt file which said if the upgrade fails, just pull the battery out and restart it - phew!
