A new Samsung device headed to T-Mobile has popped up this weekend. Meet the Samsung T699 smartphone that we are hearing could be a Galaxy Nexus variant for the Magenta carrier. In a newly leaked user agent string the device has roared its head and started the rumor mill churning again.

We’ve seen reports that T-Mobile was getting the Galaxy Nexus, but that’s all we ever heard. A few weeks back the Galaxy Note for T-Mobile leaked too but it has a 1280 x 800 resolution. This new device appears to be rocking a 1280 x 720 display just like the Nexus. It could possibly be the Galaxy S III but that is very unlikely given the T699 codename. We’ve been hearing the T999 will be the Galaxy S III when it arrives on T-Mobile.

According to the folks from TmoNews this mystery Samsung T699 will be arriving sometime “soon” for T-Mobile and we’ll be hearing more shortly. They did report the T699 number was a recycled product number but appearing again with a 1280 x 720p resolution is the interesting part. Would you buy a Galaxy Nexus on T-Mobile in 2-3 weeks if available, or wait for the Galaxy S III? Stay tuned for more details.
