What do I need to go to program an iOS system?

Just out of curiosity what do I need to know to program and iOS system for the iPhone to upload to Cydia or something (C++ or JavaScript etc…) Thanks!

Most iOS apps are written in Objective C. You can also use C, C++, maybe Java, Python, and Pearl?

Typically you use Xcode on a mac, but I think I've read that people are using a Windows PC also.

You should go to Apple's web site for developers to get more info.

If you don't know any programming at all, then you have a long, steep learning curve to tackle.

I'm sorry, but if you can't find the answer to this on Google, you will never achieve your goal.
If you are serious about putting an app on Cydia, start learning how to figure things out on your own, now.
