no, not device id, for example on incoming call screen,before this form had id 2400, now its 1500...unless you add content or react on events on phone application screens you won't notice it
if uou use only documented phone api it seems to work same way as it did on 650 and 700p -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
