More evidence of the name "Galaxy S3" comes by way of SamMobile today, which notes that two phones by that name can now be found in some versions of Kies, Samsung's PC-based smartphone companion software. The two handsets in Kies have model numbers GT-i9300 and GT-i9300T; i9300 is already widely believed to be the S3's correct model number, and the "T" would indicate a variant with different frequency support, just as it does in the Galaxy S II range. SamMobile notes that the phones seem to have placeholder images, not the real thing — and considering that the company has gone to the trouble of enclosing existing prototypes in fake shells, that should come as little surprise. Leaks aside, we're not expecting to have the full story until Samsung's May 3rd event.
