One method I have seen my entrepreneur clients use is to project current technologies into the near future to try to fill an upcoming gap. How can you apply a similar technique? Think what new (and old) mobile technologies/areas are on the near horizon such as NFC, HTML5, Android tablets, rugged devices, mHealth, enterprise and now I suppose Google Music. Create some new solutions or services related to these areas. As I previously observed, it might be best if such ideas are operator or platform agnostic.
