That's horrible that they didn't give you a choice. It would have made more sense to give you the Touch Pro 2 instead of the Imagio, because the Touch Pro 2 has similar features to the Touch Pro (physically). Anyway, the Imagio is a great phone, and you should enjoy it! As for the apps, probably anything that worked on your Touch Pro will work here, I recommend Shazam for quick song Identification
