Diamond Died, RIP

[tcatnat]

I have a question. Last night my Diamond died and nothing I did could revive it. It boots to the Windows Mobile start screen (the green one) and freezes there. I cannot even hard reset. Good thing for warranties.

My question is, I have a recent backup but I only back up the main memory. I have a bunch of apps installed to the internal 4GB storage. What happens to those apps if I restore my backup? Basically what I'm wondering is if you install an app to the internal storage does it place nay files in the main memory? The last thing I want to do is restore partial apps and have a total file mess on my new device when it comes.
