Wirelessly posted (7250: BlackBerry7250/4.0.0 Profile/MIDP-2.0 Configuration/CLDC-1.1)
My RIM contacts have mentioned many times that a "ruggedized" version of the BB is forthcoming. They have not indicated which form factor will be used.
However, my impression is they like the 72xx profile...almost all of their product is available only in the smaller profile. So you may want to hold onto that 7780 for now!
