Happened to me today: I wanted to transfer some MP3 files to my E61, but it said it couldn’t switch to mass storage mode because I had set the text message storage to the memory card.
My guess is that the messages being displayed on ActiveStandby are fetched from the storage card, so the phone can’t go to mass storage mode. How hard can it be to program concurrent access to the memory card file system?
Sorry for ranting – but I’m fed up with that kind of crap. This is supposed to be a business phone, so please take the time it took to implement that error message to implement concurrent access to the memory card.
