I am a VERY long time user of handhelds, starting with a Psion Series 3a and then switching to Windows Mobile when Symbian/Epoc was not able to handle to the new internet protocols. WM has been a very interesting platform to work with because of the ability to use 3rd party apps and multiple accessories including bluetooth GPS receivers. Yes, I know that other platforms have similar capabilities, but WM was able to multitask and that's what I wanted. For example, listening to my mp3's while being guided to my destination via TomTom while I covered 14 states for work. I loved being able to take my information, games, maps, email, documents, etc. with me wherever I went, knowing I had a backup on my computer should anything happen to my device. However, this new iPhone is the first NON-windows device that has really caught my attention. I am disappointed that it still lacks native MMS and that the battery is not easily changeable. In the future, I am hopefull that 3rd parties will solve these two issues and my disappointments will become moot. My question is, do you think it will be possible to listen to music WHILE using the GPS/Map functions?
