After four long months,the Android v1.5 “Cupcake” update has finally been made available to the masses in the UK and USA. As April 29th came to a close, the first reports of update notifications came trickling in, and they’ve continued throughout the morning.

As usual, it’s not hitting every handset at the same time. Don’t panic if you’ve yet to see the prompt – you’ll probably see it within a day or two, tops. This one’s a big one, so look forward to some exploration. You’ll have video recording, stereo bluetooth, onscreen keyboards, live folders, new widgets, a brushed up browser, and a slew of performance upgrades and bug fixes to check out. Be sure to drop a comment and let us know when it hits your handset!

(Our favorite part: Though “Cupcake” was originally just an internal moniker for the development branch, the name has become official enough that it’s in the update notification.)
