Received both of mine late yesterday via UPS.
The seal on one box had been broken, although the contents appeared undisturbed and exactly like the other sealed box. SIM cards were bagged, and still 'intact' inside their 'credit cards'. Other items included were batteries, USB cables and wall chargers, all sealed in their bags.
Have to say I am loving WP 7.5 and the Titan. I can see why others have been praising the simplicity and elegance of this OS. Set up was a breeze, and it really is a fast and smooth interface.
Cheers!
