I can get a dropped call almost everytime at this particular (starbucks) hotspot. And another (starbucks) hotspot downtown. I can either be on a call on EDGE and it will about 50% of the time "CALL FAIL" when it switched to UMA. I can also place a call while on UMA at these locations and walk to my car, or walk out to work and get the same thing "CALL FAIL". What exactly should I be looking for or talking to t-mo about the "potential handset or account problem" you are referring to? Keep in mind this is my third 8320 and fourth simcard so I would hope it wouldn't be another of those issues but I suppose you never know...
I still do have a open trouble ticket with t-mo engineering, so if there are specific questions I can ask them, I would love to...

EDIT: I just got home from work and when I pulled up to the house while I was on a call it dropped and I got "Call Failed" when it went over to UMA (on my t-mo router).

If you suddenly lose wireless signal that set up can't happen or doesn't have a chance to complete and your call is guaranteed to drop 100% of the time.

A good test here would be to stop at the Starbuck's, place a call, and walk down the street a bit until you leave wireless range. If your call drops then you may have a handset issue or there could be a problem with your account.

I've done trouble tickets for dropped UMA/GSM handovers before so it's something to consider if this issue continues to happen.
