I have dual accounts for several of Google's services (i.e. the same two accounts for Picasa and Google+). As I want to pull this info onto my HTC G2 I've set up those two accounts on the phone. Is there anyway to change the default account? For example, now when the Market informs me that newer apps are available it always defaults to only giving me this notice for my secondary account. It seems that the default apps installed by Google (Books, etc) are automatically registerder to all Google accounts on the phone.
