My LG cell phone (Verizon) came with a program called EZ Tip Calculator, which allowed the user to input a number, from which it automatically deducted a percentage to produce a gratuity amount.

My BlackBerry 8700c (Cingular) lacks such a program. (I know I can use the built-in calculator, but a specific calculator for tips is much easier for the mathematically challenged like me.)

I tried Google, and found this page, but the link to Mobiledia Forums doesn't work.

Anybody know where I can download a tip calculator for a BlackBerry? Many thanks.

Update: Well, it has more functions than EZ Tip Calculator, but it's interface is confusing -- not at all user friendly. Still, it's the only such program out there for BB, so I recommend bistroMath.
