That pinch-to-zoom update for the Xperia X10 that Japanese customers got an early lead on is now rolling out around the globe according to a new blog post from the boys and girls at Sony Ericsson. That may not be the most interesting part, though: they're also chatting up a future firmware update that'll enable ANT+ support on the Xperia X8, X10 Mini, and X10 Mini Pro, a capability baked into the chipsets on those devices that Sony Ericsson hadn't previously exploited. Theoretically, that means that heart rate monitors and other wearable fitness gear -- a market where ANT+ has really blossomed -- could connect directly to your phone rather than passing through a computer with an ANT+ dongle first, perfect for analyzing jogs on the go. Of course, workout technology is always more appealing than the workout itself... but if you can solve that problem, Sony Ericsson, let us know. You can find us on the couch over there.
