Im wondering if I can use a MacBook with OS X to sync and update my Rogers Nokia Lumia 900 to Tango? I've been browsing the forums and decided to register. I don't have my Lumia on me right now and typing this from my iPhone which I use for work. I might use my wp phone for work as soon as I figure out how to develop apps on my windows computer or Mac for all the windows phone. I will support Tango and up for my apps. So you won't be losing out on development support. I'm new to windows phone and development so any help will be appreciated. Thanks, Elizabeth Mauthe aka ludicrouskitten
