Like Foxglove said, it's the same device, but corporate users (Vodafone's bread-and-butter client base for BBs) will get them first, several weeks before everyone else. Most likely this is due to the initial crush of orders with a limited supply. It may also be a little "thank you" to corporate (BES) users - give them the new hotness before everyone else and let them get the admiring/jealous looks.
