upgrade app on jailbreak device
<p>I have a free app. I also make the version for jailbreak iphones.
The problem is that the normal upgrade on iphone is just run updating of appstore app.
But for the version works on jailbreak device, I hope I can check whether the new version existes,
if sure, it downloads the version from web and installs it on the device automatically.</p>

<p>What kind of sdk I need to call for install the ipa file on jailbreak devices?</p>

<p>Welcome any comment</p>
