Looks like all of the models have something good, but all have something missing. I appreciate differentiation, but this seems silly. Tmo gets 16gb built in, but no flash or FFC (not that I would us a FFC). Sprint gets a keyboard, but not the 16gb built in. Verizon's seems the weakest features of the litter in regards to built in memory (2 wimpy gigs) Best option to me would be the Sprint verison, but with 16gb built in. BTW, where is the flash for camera on the Tmo? Crazy. Samsung should change name to Sillysung. These differences would only be good for the consumer if on the same carrier and still options are too spread out. None of the devices have the complete feature set of the models. Makes zero sense to anyone but Samsung.
