Hello, Im sure you're all aware of the low transfer rate of iPod touch users over to the 3.0 update.

I recently submitted an update and now the game is only avalible to those with 3.0 installed, this is cutting down sales. I know Rolando 2 has submitted a 2.1 version of their game, does anyone know how you go about doing this?

Thanks for any help

You need to build with an older version of XCode and select the earlier 2.2.1 SDK.

(And still test the app by running it on a 3.0 device )

You can build for 2.X with the latest xcode... thats what I did.

Thanks a lot guys, good to hear that its so simple.

This isnt the case for now but if i were to add 3.0 features to a future game is it possible to have both versions or will it cut me out of the 2.X market?

You can weakly reference (I think there's some other name) the 3.0 framework and then directly use the 2.x. Then test if they can perform the 3.0 features and only use them if they can. There are tutorials posted (somewhere, I don't recall) that show how to do it.
