Ridiculous waste of time and money

This crappy app works about once every month... never when i need it. When I try to open a zipped file, I usually get a message saying "Mail cannot open this attachment", even though I have purchased Zipbox precisely for this purpose. Nothing I try to resolve this works. This is one more reason that the iphone makes a crappy business device - especially for corporate e-mail support.
