I got a Lumia 920 and already installed Photobeamer app. I run the app, select a photo and it says " On your friend's phone, go to www.photobeamer.com".When my friend goes to PhotoBeamer, we then see a "barcode" logo and at the buttom it says "Install". I select Install and it gets us to a page where the app should/could be downloaded from!! But it says "this app is not compatible with this phone". my friend's phone is an iPhone 3.
