Nothing causes panic to an Android developer more than the fear that they accidently deleted the keystore file used to sign their applications when there's no backup of it. Now there is a backup and there is an updated version of the TWiT app.
The update should improve some of the delay of loading new Activities (views) and removes the rather pointless view of of the Player moving the Play and Stop controls to the action bar. There will still be some delay loading the Chat and Calendar views as they have to pull webcontent down to the Android Device.
