Carrier Unlocked / Unbranded Phone Advantages

[andrelamont]

I am curious,

I was told that I could have my AT&T Lumia 900 unlocked in November but now, I am wondering what does that really buy me?

Will I get updates sooner?

Will updates still have to go through AT&T

I know it'll make it easier for you to sell it if need be.
