However, they're now announcing that it'll have to wait until late October as they said, “we need a couple of more weeks before we are ready to start the roll-out.” Previously, the availability of this long waited update was penned down for a September release, but now that's all but a repressed memory at this point.
Still, it's hard to believe that owners are still waiting for just Android 2.1 when many other manufacturers are also busy in pushing out updates to their handsets – but they're obviously targeting Android 2.2 Froyo. Regardless, there looks to be some extra goodies being thrown in by Sony Ericsson such as HD video recording with continuous auto-focus for the Xperia X10.
