I noticed the update in the market today.
Does this bring all Android devices up to the version that shipped with droid or is there an update for us Moto Droid folk as well?
I don't. So I'd have to assume that when I go into the Market app and see an update available, that it is indeed for some application on my phone, whether Motorola installed it, or I did.
Sometimes I'm notified...sometimes I'm not...
I check the Market on my downloads about once a week and if there are any updates, I'll fix them at that point in time. If I'm notified, then I'll update that app immediately.
