I did and so far I have had to drop back down all the way to 0.64 tmo OS due to dropped calls and breaking up call quality. I hadn't had it on any OS until .101, but in downgrading, it remained on .73 and so far seems resolved on .64
I really don't get it, it doesn'tr make sense, .73 worked great the first time around. I am not completely willing to blame the OS. Once I establish that .64 is ok for sure (more time) I probably will give .101 a try again.
In talks with tmo BB help about this and my GF's call dropping /quality probs on her tmo 8800 (probably bad SIM) they encouraged me by telling me that the new tmo OS should be out soon! I hope they are right. What does "soon" mean anyway?
