transfer between android/iphone/windows phones from the main menu

to make the software as usable as possible, make it possible from the main menu to be able to transfer files/music/data between Android/iphone/WMobile phones.

The menu should be striaghtforward, first menu should be select phone host to destination, then he software should decide whether it needs conversion or not, then show 2 screens, one for the host phone, the other for destination phone, and then let users drag and drop and click OK. The intinal menu should be diffrent for different transfers.
