Right after Helio worked with Pantech on the Ocean, Pantech cranked out the strikingly similar (albeit with less spring-loaded-slider goodness) Duo.

This morning, Pantech announced that not only had all the Duos currently sitting on AT&T’s shelves been bumped up to Windows Mobile 6.1, but that the folks back at home could get in on the fun too. If you’ve got a Helio Ocean 0.8 Pantech Duo sittin around, head over to the product page for the update kit. As always, be sure to back up your data before diving in – making the switch does involve having all your data erased.
