Broken iPhone, Replaced with HP Veer 4G (as Temp Replace, need apps)

So my HP Veer is coming today, after my iPhone overheated and Apple refused to replace it (w.e. I'm planning to move to Lumia 900 when it comes to AT&T)

But anyway I can't wait to actually see what the hype about the most intuitive OS is all about, I was just wondering if anyone had any good App recommendations that I have to try before I replace it.

Also whats the status on jailbreaking to place old school games, I would love to revisit some classic RPG's. (Plus the screen size would provide an experience very close to the original expierence.
