Cliff Simpkins, product manager at Microsoft just tweeted about this matter. If you are an AppHub member and you didnâ€™t receive an invitation to download Windows Phone Mango OS preview, there is a solution for you.
You can simply fill out a form with your AppHub details for WPDev OS Pre-Release Request . Microsoft will then send you the invitation to taste Mango after verifying the account.
