I'm going to be able to replace my Hero in a couple of months and was wondering if anyone knows why the Galaxy S2 doesn't have NFC on Sprint when all the other versions have it, and if there is something that can be done about it (I heard the NFC is in the battery of the Galaxy Nexus, if it is also in the battery for the Galaxy S2, can I just buy a battery from Verizon/AT&T and put it into this phone). As it currently stands I'm trying to decide between the S2 with an SD slot and no NFC or the Nexus with NFC but no SD slot (all of the other differences don't much matter to me).
