i9100 = NO

i9100P = YES (it's an i9100 exactly, but with NFC. ROMs for i9100 will work, but need to be modified to show NFC settings, otherwise no NFC options will show)

i9100G = NO, it's completely different from the i9100 hardware (TI-OMAP instead of Exynos). ROMs from i9100/P don't work.

T989 (T-Mobile GS2) = YES, but it's completely different from the i9100 hardware (Snapdragon S3 instead of Exynos). ROMs from i9100/P don't work.

i777 (AT&T GS2) = YES* , stock ROMs disable it. ROMs from i9100 work because they're the same phone (it's really an i9100P because it has NFC) but you need to modify button layout or the buttons won't work in the ROM.

D710 (Sprint GS2) = NO

So my question to you is if stock roms disable NFC on the i777 then why did my box say that it is NFC equipped and I was able to use it stock?

On my Australian T model it is not supported(doesnt work) but my P model is and (i9100)my standard one has no nfc

ICS upgrade might have re added it. Google "AT&T Galaxy S 2 NFC disabled".

my sgh-i777 has no indication of NFC on the box and was unusable stock. It does say "Near Field Communication" on the battery but I was only allowed to read some tags with a custom rom a while back. I'm on AOKP now and haven't tried anything with NFC as I gave up on it a while ago.
Is NFC fully functional on your i777?

The i777 is really an i9100P (European I9100 with NFC). So yes it should fully work on a ROM that supports it.

so thats mean can;t work for my gt1900..oppzzz

My sgh-i777 obviously came with it but turned off from carrier att. But I've been using nfc since gingerbread a dev entropy got it working back on 2.3.4 release from att. However the problem we do have is the lack of secure element which is why we can't use Google wallet for instance. Theirs been alot of debate over the secure element factor but besides that its fully functional.

There's no debate; it needs to be there or Wallet won't work. End of discussion. Any other NFC stuff should work.

Great info.

My brother just got the Nexus 7 and I was able to Beam a site I was browsing on chrome to him (I'm running AOKP btw). So it does work

But he tried to beam me a picture and it said the other device doesn't support receiving large files via beam ?

So now I know that my nfc works, what cool things can I do?

Pretty much anything else that newer NFC phones can do, except Google Wallet because that requires a separate chip called a Secure Element. NFC itself is a very slow, weak protocol. You can beam text easily, which is probably what happens when you beam something like a URL. But beaming a picture would take a looooot of time and power. So I think what happens is the NFC chip initiates a Wifi-Direct (Wifi-to-Wifi) or Bluetooth transfer.

Try buying Samsung Tectiles and using the app to trigger actions with NFC.
