PSP Media Manager Update
Wednesday October 29, 2008
If you own the retail version of Sony's Media Manager software, you'll be able to get an upgrade for free, via the firmware 5.01 update, which enables direct access to the PlayStation Store from your PSP. The upgrade lets you access the PlayStation Store from your PC, and helps organize your PSP downloads and sync them to your PSP. There's no Mac version, naturally (because apparently I must be the only Mac user on the planet who also has a PSP). (Via Gamasutra.)
