also, saw this post on o2 forum - this guy seems to make a lot of sense;

"People who ordered on T-mobile will have their pre-orders honoured.

the device is exclusive to Nokia Online Shop, Nokia Flagship Stores & Mobile Phones Direct until Jan 2010. This is further confirmed by Play.com moving their pre-order expected date to 31/12/09 and buymobilephones.net (who were offering on O2 & Orange) delisting pre-orders & showing as coming soon... Incidentally those who pre-ordered from buymobilephones.net are now told to wait until January as well."
