I use a stock Thunderbolt with the most recent GB upgrade. I like it a lot, but I'm having an issue. My calendar notifications do not work if the notification time is anything other than 12 hours. Even at that, it is hit or miss whether it will work. I use the calendar app on the phone synced with my Outlook calendar (not Enterprise) using HTC Sync to sync the two. Any thoughts, help, or advice? Thanks in advance.
