maintaining compatibility with previous iphone devices and os's -


How easy is it to return the OS to a device, i.e. iPhone or iPod touch?

I know Apple still offers SDK 3.1.3, but if you want to test it on that device which is currently version 4 of OS?

The more people use the highest 3.x OS, the more difficult it is to be.

Just do not have enough testing in your code for testing various OS versions, nor do 3.1.3 install and test in the simulator. You also need to test on the actual device, do not you?

How are people coming around this?
