It's a luck of the draw thing- calls will ring through when connected on
GSM/EDGE if data isn't actively being transferred (like a web browsing
session when you're reading rather than loading a page) but if data is
actively being transferred (like a file download or synching e-mail with a
server) T-Mo doesn't interrupt the transfer for whatever reason ("that's
just the way it works" they say.) Ironically, if I fall back to 1G
(9.6kbpsCSD!) the data call will be dropped when a call comes in. One month,
as a test, I switched my e-mail settings to use CSD over adialup ISP to
reduced missed calls, and ran up over 800 minutes of CSD use, so I switched
back to unlimited GPRS!
