Android :: A Verizon Droid Puzzle

I am based in Germany and publish the "Last Call Widget" on the Android Market.I have been steady improving it over time, but one group of users still complain about it not working on their devices.My widget listens for the "android.intent.action.PHONE_STATE" intent, and then sets an alarm to update the last call UI in 20 seconds, then 60 seconds, then 5 minutes, 1 hour, etc.This works reliably on all my test devices, even with aggressive task killers (try it yourself). Unfortunately I have a cluster of users with Motorola Droids on the Verizon network who complain that the UI does not automatically update. I believe Verizon is a CDMA network (we have GSM here in Europe), though the Android API docs don't specify any implementation differences.This could also be a driver issue on the Motorola Droid (we have GSM Motorola Milestones in Europe).
