Nokia N97 32GB - BT Only – Support Forum

Which variant of the N97 is this? [Nokia N97 32GB - BT Only - 184147]

Is it the Global spec RM505 (HSDPA 850) or the America spec RM507 (HSDPA 900) ?

In New Zealand the 850 will only work on Vodafone and the 900 will only work on Telecom's new network so I need to make sure I get the right model!
