The program is open to all developers, although you will have to first register for a Nokia ID, and can be paid for using a VISA or MasterCard credit card.
The membership benefits include:
- Windows Phone Dev Center Membership ($99 USD retail value)
- Buddy Notification API calls (12 million/year –up to $1,200 USD retail value)
- Telerik UI controls ($99 USD retail value)
- Two Nokia tech support tickets (up to $198 USD retail value)
Since the program includes Windows Phone Dev Center Membership (either joining or extension for existing membership), which is required to publish a Windows Phone app, canny developers should join the Nokia Premium Developer Program as they will almost certainly be spending $99 anyway , and may like to benefit from the other membership perks (although there is currently a special offer on Dev Center membership for $8).
Developers who are members of Nokia's existing premium developer programs (e.g. Nokia Launchpad), or are Nokia Developer Champions, will receieve one year of Nokia Developer Pro memebership for free. Nokia notes that such developers will receive an "email soon with a code that entitles you to a free year’s membership in thenew program".
