(New) About why GPRS stays on with Motorola MPx200 with WM2003 update
Windows Mobile 2003 has "always-on" GPRS. What you´re seeing is normal,
and you shouldn´t really worry about it. Your GPRS plan is likely per
byte or flat rate, and you won´t be using any extra GPRS by having it
sitting there ready for you to browse/get mail/whatever.
