comScore remains a leading source for measuring key mobile trends, and their latest report is giving me a sense of deja vu. If we look at the results from the three month period ending November 2011, it’s safe to say that not much has changed. Samsung still remains the top OEM with 25.6 percent of U.S. mobile subscribers (up 0.3 percentage points), followed by LG with 20.5 percent. RIM finished last out of the top 5 with a 6.5 percent share (down 0.6). As for mobile OS platforms, I bet you can guess who’s leading.
