If a user has their friends list available for view in mobile, when you click onto their list it has these options at the bottom of the screen -- All, Top, Online, New, and Birthday.
If you click on "Birthday," it gives you all the user's friends who have made their birthdays available to their friends. So far, it looks like they've only gotten to the dates ranging from Jan 1 to Feb 28 -- this is the only range that shows up so far. I checked a number of profiles, including my own, got the same results, and then checked it out on Myspace CEO "Tom."
Tom has over 1,200,000 "friends", and clicking "Birthday" brings up 19,567 pages of them -- ten per page, so over 190,000 "friends" -- all with birthdays from January and February.
I would guess that birthdays in the month of March and April will be next, etc, until they've gotten them all.
This only shows up in Mobile, not regular Myspace pages (I can only access Mobile from my pc, not a phone, but I assume it shows up via phone too ??).
So the point is, if you have your birthday available to your friends,
and your friends list viewable to everyone on Mobile, your birthday could now or soon be viewable to
anyone using Mobile. It might be worth checking to make sure you don't have this combination with your profile.
Identity thieves could have a field day with real names, locations, and birth dates.

Also noticed that the fonts in Mobile are quite a bit larger now, and the colors more intense. Wonder what other changes might be coming, and if any of them will open any loopholes for us?
