hey guys i was at work today and saw someone looking at cell phone cases! i took a look at the cell and it was the 8100! i asked and sure enough this guy worked for RIM and let me play with his 8100! this unit is awesome, the camera is 1.3 the quality is ok i mean for what it is its good. the micro sd slot will use w/e the max size of the card is so anything right now 2gb is the max u can get but if there was a 4gb then it would work with that as well...the 4.2 os is awesome and the video playback on this is out of this world...for the ppl who have been saything the screen quality is better on the 8100 then the 8700 they are wrong! its the same screen just is an "almost" sq shape! but wow this was the highlight of my day and what a great unit this thing is! anything i left out just hit me up!
