One of the MFM taiko told me that Papago will update its android software by this year end, if not early next year to X6. The current problem is not certain phone model that can't run Papago, its Papago SEA version not compatible with the OS/firmware that runs the phone. Most of the current Andoid phones already ship with 1.6 or even 2.0 firmware, Papago will need to upgrade or loss of market share here.
