Ah cool, well perhaps I will be hitting you up with questions Thanks for the welcome.

Not sure if you're still adding to this list, but I've worked on several WP7 apps, as well as some Javascript and ActionScript based projects that have been deployed to iOS and Android, and am also moving into Objective-C. In spite of it's limitations, I'm very interested in building cross platform apps using technologies like PhoneGap, Corona and Flash.

littlebigman,

There certainly are ways to build apps cross platform. I guess the first thing will be to choose what dev environment will a) target the platforms you want to deploy across, and have the quickest learning curve for you based on your background. I think it's ok to start with a "simpler" language, and learn other languages after you have some understanding of basic concepts.

I put together a diagram of the dev stacks that exist for building mobile apps so take a look and you can hit Google to find out more about the ones that are of interest to you:

Also, if you really want to learn Objective-C, I've found that one of the best (FREE!) sources are the lectures from a course at Stanford. You can get them here:

First, you should probably determine which version of BB OS you want to build for. Currently all phones run on BB OS7 or older. However, they are moving all future phones over to their new OS which I think is called PlayBook OS. There isn't much overlap between coding for the old and new OSs.

OS7 and older can be done either using Java or HTML/Javascript.

1. Java allows you to create 100% native apps that have access to all native BB device functionality.
2. If you want to use HTML/Javascript (called a Webworks app), it uses a native wrapper that contains a webkit browser to display the HTML content.

PlayBook OS development is a little more varied.

1. Native development is done using C/C++.
2. You can take an existing Android app and package it as a BB app using their Android packager
3. You can also use HTML/Javascript as mentioned above.
4. You can create an AIR app using Flash and/or Flex SDK. This runs on top of the Adobe AIR runtime on the device (the runtime can be packaged with the app).

There are a lot of options Here is a chart with some links providing more info:

I haven't done any XNA dev on a real project, but have looked into it. Is there something specific you needed advice on?
