While Sony Ericsson may not have released the dual touch update outside of Japan yet, the folks over at XDA have once again, been hard at work. The recently released dual touch update can now be applied to any Xperia X10 handset. You will need the latest version of flashtool and the Dual Touch FTF file available from here.

The debate about whether Sony Ericsson’s flagship Android handset, the Xperia X10, supports multi touch or not, has been on going pretty much since the day the handset was announced. We heard some say that the X10 was capable of multi touch and even some videos showing multi touch on the X10. Then the day came when Sony Ericsson themselves officially announced that the handset would not support multi touch. Despite that, there have been many questions arising and doubting the “confirmation”. The speculation that the handset may support multi touch rose again when the X10 was due to be released Stateside, as the Sony Style website had the handset pegged as having a four inch multi touch display. That little detail was however removed once the word spread throughout the internet.

Despite numerous confirmations now by Sony Ericsson saying that the Xperia X10 does not support multi touch due to hardware limitations, some have still been left wondering if it really does. As after all, Sony Ericsson had previously said it did support multi touch, with even the US Sony Style website listing multi touch as a feature before the launch of the handset.
