iPhone:Can 3.1.2 built iPhone app installable on 3.0/3.1 devices?
<p>I have built an iPhone app with 3.1.2 SDK. </p>

<ol>
<li><p>Can it be able to deploy on my iPhone 3.0 or 3.1 device using the same provisional profile using Xcode? </p></li>
<li><p>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?</p></li>
</ol>

<p>Thanks.</p>
