Not sure if it happened with the RC29 or RC30 update but they removed the setting option to "Allow File Browsing on Computer"(or something like that) from the SD Card Settings menu. I just got both updates pretty close together and I couldn't figure out why the phone wasn't showing as a Removable Disk in My Computer. Well, now when you connect the phone you will see a USB icon show up in your notifications bar. You have to select that and choose to "Mount" the phone/card. Done. Still not sure if I like the new way. Seems like unnecessary extra clicks to have to choose this option each time you connect the phone. What do you guys think?
