Are you using the device more? 10 hours does seem pretty quick, but I've never had an iPhone that could last more than about 36 with any real usage. Did the decrease correlate with the update to OS 3? Did you re-pwn the firmware for the upgrade, or just auto-update in iTunes? I've seen some weird things happening with jailbroken 3.0; if you built your own, you might want to consider reinstalling it.
