Apple’s new iOS 4 is available for iPhone 3G, 3GS, 4 and iPod Touch G2 and G3… but not for the original iPhone or Touch.

Okay, so what?

Well, as developers update their apps to work with the new OS, the dead-ended devices will slowly lose their ability to run updated software. I’m my case, this is actually going to be a huge problem because I sync both my iPhone 3GS (with iOS 4) and my iPod Touch G1 (running iPhone OS 3.1.3) to the same iTunes instance on my computer.

iTunes or the iPhone will compel software updates as time goes by… and because iTunes centrally manages the apps, it’ll slowly invalidate everything from running on the Touch – eventually it’ll only run the base apps that came with OS 3.1.3 and none of the 3rd party stuff.

Kinda sucks.

Not sure what I’m going to do about it, other than maybe using one of my other Macs (Mini? Laptop?) for syncing my Touch, but I’ll lose podcast-synchronization and I’ll have to link the music libraries – it’ll be a serious pain the butt.

Any ideas? (Other than getting rid of some perfectly good hardware.)
