I am having the same dropping of calls since I've upgraded to .180 as well.
On the phone with a RIM support rep, he had me make a minor adjustment in my router configuration (changing the beacon interval to the lowest interval supported - I believe it I changed it to 20 msec). Anyway, after making that change, he told me to turn off my Mobile Network connection and called me back to test if I would experience a dropped call -- of course, just as you would expect, the call worked flawlessly and I was hopeful.
Then I came home last night and again, another dropped call within 5 minutes.
In the spirit of attempting to isolate the issue is I turned off my connection to "Mobile Network" off while at home and connected left the connection to my wi-fi only active. Again, I did some test calls and I didn't experience the dropping of calls issue.
Of course, this configuration isn't ideal and defeats the purpose of the flexibility the automatic switching between networks is supposed to provide however does appear to me that this is where my issue is occurring. I will report this to the technical support but if others experience this same behavior maybe it will help then isolate the issue for a fix.

Last night it happened again, about the same time frame (15-20 minute phone call conversation) and than I used the phone again (mind you network turned off throughout this time) and it lasted the 32 minute conversation.
At the moment I am just logging where (how far away from router) and when (time frame) it happens to be able to call the T-Mo reps and give them an exact idea of what I am experiencing.
