IPhone:Can 3.1.2 built iPhone app installable on 3.0/3.1 devices

iphone

I have built an iPhone app with 3.1.2 SDK.

  1. Can it be able to deploy on my iPhone 3.0 or 3.1 device using the same provisional profile using Xcode?

  2. If i submit that app which built with 3.1.2 SDK, will it be able to install on iPhone 3.0 or 3.1 version users through AppStore?
    If not, how can advertise that my app can be installed on iPhone 3.0, 3.1 and 3.1.2 as well during submitting it in AppStore?

Thanks.

My understanding is that the version of the SDK that you develop with determines the minimum version of the device that you will deploy to. So, unless you need any of the 3.1, or 3.1.2 features then just deploy to the store using the 3.0 SDK.
