Probably about the only downside to the iPhone 5 vs. Lumia 920 comparison charts in Lumia’s favor was the bluetooth profile. When originally announced, the lumia 920 and even the 820 did not have the latest and greatest bluetooth 4.0 stack.
Surprise surprise! As if to aggravate the iPowers at be, both the Lumia 920 and 820 will feature bluetooth 4.0, this has been confirmed through FCC documentation. Once again, the Lumia 920 and even the 820 if you feel a bit ignorant are hanging Apple’s iPhone 5 out to dry in the spec race.
