Hey guys, I've been debating whether to buy an unlocked version from the UK Clove website or the Expansys-USA website. The Expansys-USA is much cheaper, however it seems some people are getting mixed products from various vendors. So I wanted to know which of these two would be best. My questions are as follows: 1) Upon researching this forum, some phones come with and without factory seals (i.e., some NewEgg users do not have seals). Does anyone know if Expansys-USA or Clove is factory sealed? 2) Which one would give me a working US adapter (not an add-on)? 3) Anyone know if there are fundamental hardware differences between the phones of different countries? I know India S2's DO NOT have NFC... but what about the versions from Clove (I assume UK) and Expansys-USA (I also assume from the UK)? Thank you!
