i work with an indirect agent of verizon wireless. we dont sell a lot of pdas, nor do we really have any in stock, yet i still have questions to answer and "dummy phones" to show. im sorry to say that i really dont know much of anything about the data side to the phones. heck i dont even know what a "platform" is! i know features and what they can do, but i dont even know what im talking about! can someone please explain to me (like in simple terms) about the softwear they hold, about tethering and syncing (how to do it, what i need), and other things like that (cant think of all the questions right now. i know about the Q the most (since my bf has one) but i know next to nothing about the treo and the blackberries. im read the specs and took the training, but i still dont understand....please help!
