I quickly realized my mistake after I bought my 950 from ATT. 1) Microsoft's is unlocked 2) Microsoft's gets all the updates faster (firmware) 3) Microsoft's is dual sim (not that I need that). So when I broke my AT&T 950's screen so severely I could not read emails - I went to the Microsoft store to buy a replacement (even though I hear ATT's 950 is reduced to $300, vs $399 at the Microsoft store). What I was very surprised at is how much longer the Microsoft 950''s battery life is!!!! I even forgot to plug it in one night and it lasted the whole next day. This would be unheard of with my AT&T 950. Now to be fair, I have not compared firmware versions - but wow - what a difference!!

ps.. just checked the Microsoft firmware and it's 01078.00053.16236.35005 and i'm not sure what my old AT&T 950 was running.
