What are the birthday rewards for Xbox Live's "MyAchievements" promotion?

Solution 1:

Just got my birthday reward email from Xbox Live. It said the following:

Hi Klokworkk,

Happy Birthday Month!

Congratulations! This month you'll be another year wiser. But what's a birthday without a sweet surprise? Try this: Enjoy 20 Microsoft Points as our gift to you. Use it toward anything you wish in the Xbox LIVE Marketplace. Your birthday Microsoft Points will be automatically deposited into your Xbox LIVE account by the 15th of the month.

It's just one of the fun extras you get for reaching CONTENDER, CHAMPION or LEGEND status on MyAchievements from Xbox LIVE Rewards. Now, take a deep breath and blow out those candles!

Hoping your birthday wishes come true,

Xbox LIVE Rewards Squad

So it looks like they just give you 20 MSPs for your birthday. I guess it is better than nothing, lol.
