For anyone looking, here's the link from Samsung: http://www.samsung.com/us/support/owners/product/SGH-T769NKBTMB It took me a while to find, so I hope someone finds this helpful!
joerevolution, you rock.
I looked for hours through T-Mobile's online documentation and Samsung's phone documentation on why I couldn't connect to my computer via USB. It took me maybe 10 minutes to get my Blaze connected once I found your post above. Thanks for posting this... you probably saved me at least another few hours!
