microSDHC has a theoretical limit of 32gb, but these capacity memory cards not released yet . however, the stated limits for the memory cards provided are not always correct, but rest assured that the N96 will take 16gb memory cards...so you would have no problem. it is also recommended that if you do purchase a card, to purchase one from a reputable brand such as SanDisk or Kingston, and is at least class 4. other users have documented problems using class 2 cards, as data transfer speeds are too slow resulting in possible corruption of the memory card.
use class 4 cards
please throw some kudos our way, it would mean a lot to us
The specs indicate that 16Gb cards are usable in the N96:
