The five month old LG Nexus 4 just showed up on the Bluetooth SIG for a second inspection. The SIG's site appears to be down right now, but TechTastic took a screen grab which lists the revised handset as supporting Bluetooth 4.0. This is interesting, because up until now the Android Open Source Project hasn't supported the lower power Bluetooth spec, meaning that the original Nexus 4 couldn't use it despite having the necessary hardware. Judging by the appearance of this SIG listing, Bluetooth 4.0 support for stock Android could be announced at I/O later today. Coincidentally (or not), HTC is due to give to give a talk at a local Android User Group tomorrow about Bluetooth Low Energy. Oh, and while we're on the subject of a potentially updated Nexus 4, there have been more sightings of a white version in Dubai (shown above). Ripe for another I/O giveaway?
