Those of you out there who own a variant of the Sony Xperia T smartphone are about to get a taste of some buttery goodness in the near-future. According to the PTCRB website, a new firmware version of 9.1.A.0.489 has been certified for the Xperia T (LT30p) and Xperia TX (LT29i) smartphones— which effectively moves the software up from Ice Cream Sandwich to Jelly Bean. Oh and owners of an American variant of the smartphone won’t be left out either— the Xperia TL (LT30at) for AT&T is also getting a new firmware version certified with 9.1.F.1.120, which would also bring the device up to Jelly Bean as well.
So while the new pieces of firmware have been certified, it would still be a matter of weeks before we see the update land on the respective devices. Hopefully the different Xperia T owners out there will be able to contain themselves in the meantime.
