It looks as though Mango is live for most everyone. The status on the WP7 website has changed to delivering update for all carriers. There is one caveat though for AT&T which is “Delivery has begun for the HTC Surround, LG Quantum, and Samsung Focus v. 1.3. The HTC HD7S is currently Scheduling, while the Samsung Focus v. 1.4 is Testing and the Dell Venue Pro is in Planning.”  So not everyone is getting it right now..

I just checked and sure enough there it is for my HTC Surround:

Sadly I don’t think I have enough time to update it right now.. I have to leave to pick my kids up from school in about an hour, so I’ll be updating later tonight and I’ll update here then as well with some thoughts for you..
