App not installing on iphone 3
<p>I developed one iphone application using Xcode 4.2 , i tested the application in my iphone 4 it's working fine.</p>

<p>But when my client tried to install .ipa file in his iphone 3 it's not being installed in his phone,when he tried to install .ipa file he said it's saying Unsupported file format.</p>

<p>Can any one please tell me applications developed in Xcode 4.2 will work on iphone 3 or not ?</p>

<p>Note : I already set <strong>Deployment target as 3.0</strong></p>

<p>please suggest me any alternative to work my app on iphone 3 and others.</p>
