I was looking forward to the release of iOS 4.1 as it promised bugs
fixes for iPhone 3G users which also means iPod Touch users. So I
installed it last night and didn’t change any of my settings… But
guess what: This morning the battery is completely flat. So now I will
need to start looking again for some odd setting which either Apple
have changed when I upgraded or some other setting which is now
causing the battery to drain… Remember: The battery is being drained
when the device is in standby, asleep. Ho hum.

But on the plus side Apple has relaxed their restriction on third
party development tools for iDevices:
