iPhone App Compatibility with upcoming OS 4

[macbwizard]

So there aren't big issues now running iPhone/iPod touch apps on your iPad in compatibility mode, but here's a question: what is going to happen when the iPhone is on OS 4 and the iPad is still on OS 3?

Has Apple said anything about this? Will Apps that require iPhone OS 4 be no longer able to run on the iPad?

Just got me thinking today...

I expect to lose complete support for upcoming iPhone apps for awhile however I think the iPad os 4 will be phenomenal (a ton more features than in iPhone os 4) so I figure the wait will be worth it

Will probably force app developers to keep 2 different code paths, helping the development path along for iPad instead of just cookie cutter iPad support

You may not see any iPhone OS 4.0 native apps until it is deployed on all of its' platforms.
