Conversion of ipa files to xap file format

As far as we know, it is not possible to simply convert installation packages for iPhones (.ipa) to Microsoft Silverlight packages (.xap) for Windows Phone devices, which is what ipa to xap conversion refers to. You need to check if the developer of the iPhone app also offers the version for Windows Phone, because there is really no other simply way to convert ipa to xap.
