Jen let us know that SolverLabs has a really good implementation of Spider and Solitaire (Klondike) for BlackBerry smartphones called Spider. The game allows you to play both of these hugely popular card games. I remember Magmic used to have Spider game back in the day that I used to be addicted to but the SolverLabs version seems to have better controls. They have also thrown in tweaks to increase the chances of actually finishing the game along with other useful additions.
Check out Spider for $1.99 in App World and let us know what you think. I just wish they had a free trial for others to try out.
