I personally write native apps. J2ME for most low end AT&T phones and blackberries. Brew (A SDK straight out of the 80's built on non-static C) for Verizon.

I personally write native apps. J2ME for most low end AT&T phones and blackberries. Brew (A SDK straight out of the 80's built on non-static C) for Verizon. Java on Android for the Google phones and, of course, Objective C on Mac OS for iPhones. I'll work with any 3 of these platforms in a given day. 2 if I'm lucky, 1 if there's a looming deadline ;-)
