I've found my Desire to have quite poor battery life so have installed Switchpro to turn off the things I don't use such as Bluetooth and GPS. I also use the widget to turn data connection off and it works well except I'm finding quite often that something is turning the data connection back on of its own accord and I just can't work out what it is! Autosync is off as are the sync options in Friendstream, Facebook, Peep and Google Mail but something is still turning on my internet at least a couple of times an hour. 3g Watchdog also picks this up as I'd used 140kb of data this morning before I'd even woken up! Does anyone have any idea what could be randomly connecting up my network data and not turning it back off after its finished??!
