As expected, Droid Incredible users are now starting to receive an over the air update that packs a number of fixes and additions. The biggest of those additions, of course, is the V CAST Apps store, which will let you purchase apps and bill them straight to your Verizon account. Otherwise, you can expect to get an updated Slacker application, a Flash update with some security improvements, some Visual Voice Mail fixes, and the ability to email attachments larger than 5MB. Look for the update to hit your device within the next few days if it hasn't already.
