Anyone find a compatible RPN calculator for the Torch? I have tried a couple that were developed for the Storm, but they do not work (cannot get the onscreen keys to work).
I really like the Pocket 10C SE that I used on the Bold. I emailed the company that makes it but have not received a response about future versions.
I saw an RPN calculator on BlackBerry App World (I think it was) a day or two ago. It wasn't an HP emulator, and it could do calculations with complex numbers.
App World / Categories / Utilities / Calculators / Neelam: a Complex Number Scientific Calculator. There's only one non-informative review and it doesn't have a free trial. However, there is an email address for the developer, so you can probably find out if it works on the Torch without having to buy it first.
