This seems to work / not work intermitently. I don't know why. I love it when it works, it's a great tool....... I'm not doing anything else with my phone in between, so I don't understand.
For now, it doesn't seem to be reliable on my Captivate. I'll keep watching for updates.
Again, I would def pay for a version that you could customize and would notify of voicemails. I'm of the mindset that a missed call is no big deal. If the call was important, they'd leave me a message and then I want that notification. But, I'm also not the typical cell phone user that has it glued to their hand/ear, etc. either.
