What apps can I change with CyanogenMod?

[jmklei0]

I recently rooted my phone and installed CyanogenMod. As you may know, the ROM comes with "better" apps for things like calculator, clock, and calendar. They look like great apps. But, I think I may want to revert back to the original of a couple of those. Mostly for the wheel mechanism they use for the numbers, instead of the plus and minus signs. I've looked on the market for these basic apps and can't find them. How do I do that? By the way, I'm also using Titanium Backup. (which, the only apps I can find on it are the ones from Cyanogenmod)

Thanks so much.
