Hiya, I'm considering buy an iPod touch for use as a casual break-time gaming, e-book reading device and general PDA function device. I'm going to jailbreak it, of course, but I'm a bit concerned about application compatibility with different versions of jailbroken iPod OS (OS X?). During my "research" of various iPod touch games and programs I read that certain programs only support certain versions of jailbroken iPod touch (unless I read it wrong). So, I was wondering if applications and games on iPod touch are 1-fits-all (at least have backward compatibility to older versions, if not requiring newer version), or is it like certain computer game mod where you'll need a specific version of the update just to run a certain mod - sometimes even requiring you to use older update just to play a mod. And yes, I know games/apps are different from pc game mods, but my lack of understanding of how jailbreaking works has led me to such concern. Pretty much - I need to know that the iPod touch that I'll buy and jailbreak will play as many games as I'll want to justify the spending. Thanks! ps. Sorry if this has been asked before! ps2. I don't want a PSP. Just in case anyone might be so "wise" to suggest that.
