Every once in awhile I find myself in need of a Graphic Calculator to help a friend and my TI-82 always manages to hide in all my junk. I used to use gCalc from gWhiz but I have not been able to find a link to the free version for awhile and the commercial version is $6.99.
A developer let me know about a J2ME project he has where he created a graphic calculator for practically all J2ME devices. It works like a charm on my BlackBerry but lacks any shortcuts like normal BlackBerry apps or gCalcPro. Still the app is free so I thought some of you might also find it useful.
