Daily testing builds are available at:
You can get to the same place by setting your opkg feeds to then using 
opkg update and opkg upgrade.

gsm0710muxd is also useful for making data connections without having to 
stop qpe. If you use gsm0710muxd then mickeyterm will be easier to use 
than minicom since it is aware of the multiplexer and will make the 
multiplexed connection for you. Once in mickeyterm issue the sleep 
command then use Ctrl-d to exit. You should only need to run it once 
after booting the phone.
