I updated my 810 to update 1 before I even fully woke up lol
I tend to wake up in the morning, check my phone, then go back to sleep.
Which I did, and in doing so I saw the article on WPcentral app so I checked and had it do the update while I took my morning nap.
Its been pretty good so far.
Though I have to say this would be much better if we had gotten cyan. Sigh.. I fear eventually without these driver updates some DP update will cripple the device (be it with battery drain or just some driver malfunctioning).
