ok...i just got off the phone with samsung and my tech support genius figures it should work right out of the box. this is not the case. there is no NFC antenna built in stock to the battery nor the cover. i have a buddy with multiple blackberrys so i will get ahold of tag and try transferring it onto this phone. previously in this forum someone posted about trying the same thing but no confirmation was provided as to it working or not. i will try to confirm. but to clarify, SGH-i757m does not have the NFC hardware to support this operation, despite the software support for it.
So that answers me for the NFC.
What about WiDi ?
