I have used my z9i for a year with my BB8900. When I switched to 3G the z9i's battery seems to be always dead, as it always shut off about 10 seconds into my conversations. I quite using it for a few weeks. When I upgraded to iPhone 4, I tried again, and have the same problem.
I email BlueAnt a couple days ago (yr warranty), but haven't heard back. Has anyone else experienced this? I don't have another phone to try it out with. I have tried the reset trick, no fix.
I guess I'll have to look at a different headset. Sucks because less that a year ago, I paid a pretty penny for that headset.
