On this day 19 years ago, the very first Sonic the Hedgehog game was released in North America and in Europe.  To celebrate the little blue dude’s birthday, Sega has slashed the prices of all of their iPhone and iPad games for a limited time, even the titles that aren’t Sonic-related.  Check out the entire list below.

iPad only:

All sale prices are valid through Wednesday, June 30th.

Don’t forget to check out EA’s $.99 sale while there is still time, and Gameloft’s $.99 sale to celebrate the launch of iPhone 4.  After this week, that shiny new iDevice should be plump full of brand new games!
