There was much wailing and gnashing of teeth when Microsoft declared that fairly fresh (and costly) Windows Phone 7 devices like the Nokia Lumia 900 would never taste its latest WP8 wares. To assuage hurt feelings and keep legacy phone owners within throwing distance of the latest devices like the Nokia Lumia 920 or HTC’s 8X, Redmond introduced Windows Phone 7.8 (version 7.10.8858), which started arriving via Zune on January 31st. It was likely hoping that the upgrade would tide legacy owners over until their contracts expired or boredom set in, at which point they’d get a new device packing WP8 — including not-too-costly models like the $249 (contract-free) Lumia 620. So the question is, will the 7.8 bone thrown at WP7 handset owners prevent them from looking at the greener Android or iOS grass across the fence? We’ve got a Lumia 610 here that was otherwise collecting dust, so head after the break to find out our thoughts.
