Third Windows Phone update supports 1080p screens, quad-core CPU

All they need to add is a 64bit OS, add a rotation lock and allow for customisable keyboards. I'd consider switching back then possibly... actually I'm not even that fussed about the 64 bit support...  I hope those dual booting options have some weight with Sammy and HTC...
