Downloaded and installed it.. and... success! Sadly, it's a little flaky for me. Flash can't install for some reason. I guess I'll have to wait for the official re-release schedule next week as this version (reported by Verizon) has bugs - no kidding. Doh! Ah well, very cool way to install the update though.
Have an HTC desire in the UK (unbranded, unlocked but not rooted) got my OTA update last week. All working fine but no real speed increase and have noticed than when you update the news widget and scroll at the same time it force closes HTC sense.
Apart from that annoying niggle the extra's are worthwhile.
