You know I actually just noticed this since going from 4.0 to 4.1 with the Hong Kong CSL. I have a 7100t with TMO and I never saw (at least that I can remember) and option to set the time between "Network" and "Blackberry" when I had the OS 4.0? I know I had the BB with me when I travled for soccer last summer in and out of time zones and I was really surprised that a device like this didnt change time zones automatically like most (all) cell phones do. I had to switch the time manually. I am not sure now what the option was on 4.0 but I am curious to see if someone running 4.0 yet could check that out ( I say that like hey go drive between time zones in your spare time...lol) and see if that is something they upgraded in 4.1.
