How do I update my phone?
So just install one of these programs, connect your phone to your computer via the USB cable, and then follow the on-screen instructions. I also strongly encourage you to check out our step-by-step guide for updating your phone on the Windows Phone website.
One last important word: If you’ve installed the Zune software or the Windows Phone 7 Connector in the past, you might actually need to update that program first and then use it to update your phone. If that’s the case, you’ll know. Just follow the on-screen instructions, restart the software, and then connect your phone.
