I plan to have a look on the upcomming Nokia Lumia 930 at my local provider store. As always I keep the unlock-question in mind.
I can't post to the Dev and Hacking forum, due to insufficient posts. Maybe a Mod can move this Thread to this section if he thinks this idea got a chance to be realised.
Wouldn't it be possible to emulate the Marketplace communication on your local PC? WP devices are able to access the internet vie USB connection and Zune. But the Marketplace on your phone blocks accessing it, when it detects a Zune-Connection. Maybe there is a way to establish the USB internet connection without the phone blocking the Marketplace. Another idea is to connect the phone to the PC via Wifi (Tethering).
Once we connected the phone to the PC and it's not blocking the Marektplace access. The PC could catch the Marketplace request to the MS servers and deliver emulated Server communication. Faked App-list and of course App-Download from the PC to the phone is the next step.
I know nothing about encrytion, certificates, signing and so on. So all I can do is to share this idea with you more experienced guys.
Yours sincerely ,
