iPads equipped with 4G are showing up in Apple's inventory ahead of the iPad 3 event according to a 9to5Mac source. This would mean that 4G would not only be for US models, but international models as well. This lines up with our recent prediction that the iPad 3 would indeed be equipped with LTE.
Two new iPhone and three new iPod touch SKUs are now appearing in Apple's inventory system. The new iPod touch models most likely represent the rumored white iPod Touch in 8, 32, and 64GB flavors just like its current black counterpart. The current iPod touch has the internal codename N81. These new SKUs are labeled as part number N81A which probably indicates an incremental update, or more likely, white iPod touch models.
