I guess you could upgrade your radio to 1.40+ and try again. They said there's a big improvement to GPS fix.
Talking about TTFF, if you are moving, or inside a building, I think it will take longer than usual to get a fix. I live in a really urban area, but once I stand still in an open area, I usually got fix in 2-3 minutes, without exception.
Someone did a test in the Trinity forum - the accuracy of the qualcomm chip is even better than that of the sirf-iii.
However, a major problem though is the lack of a software assisted gps problem that can improve the ttff time. (Though qualcomm said there's one, but until now it's still vapourware.)
