It was well-received when the video chat application Tango was released for WP7 a couple of days ago. However, the news was not great for owners of the Samsung Omnia 7 who experienced several issues with it. If you are such a person, fret no more. Word from the developers was an update will be forthcoming to address the issues on this device and the Focus (which some have reported a few issues with as well).
Fast forward to today though and we just found a Samsung-branded version of the Tango chat app. Billed as version 1.1 we're not exactly sure what's different but it is safe to assume that this has custom Sammy APIs and drivers, making the experience more reliable and bug free than the unbranded option.
Pick up the Samsung version here in the Marketplace.
