XDA-Developers forum member PavelX1 has posted up info on a pile of XPERIA X1
updates he glimpsed on EMMA (Sony Ericsson's official service software). ROM version has migrated from 1.02.936.3 to 1.03.936.6 and is labeled as R2A. Of course, there's no word on what the official changes are but first reports say the X1 now boots quicker and attaches to network faster. Apparently the SEUS (Sony Ericsson Update Service) isn't quite telling the truth when users are attempting to grab at the update, but proceeding through and updating anyway seems to be doing the trick. Usual cautionary advice from us is to read before attacking this as an ounce of precaution is worth a pound of cure.
