Are there two versions of the SII?

[animespiritz]

I just recently bought a Samsung Galaxy SII which has no physical home button on it (which I prefer) but I'm also seeing some Samsung Galaxy SII's online that do have a physical home button on it and it's not the SIII.

Is it because I'm looking at pictures of an international version of the SII?

Dial into your phone *#1234# and tell us the PDA, Phone and CSC info

There are many versions on the S2. Settings >About Phone will give you the Phone Model if *#1234# doesn't work.
