More specific details will be coming on an individual basis, but the developer relations team state:
Congratulations on receiving your new BlackBerry 10 Limited Edition device. We understand however that you were sent the incorrect device model for your region. As a result we are going to set up a swap process for these devices.
I'm really impressed that the team kept their word for the developers affected, and I'm sure a lot of developers will be even happier that their device will be upgraded soon.
