Last month, we celebrated a small win for Microsoft who published its first positive growth in the U.S. mobile market probably since before the launch of Windows Phone 7. Unfortunately that might have been a bit premature, according to comScore's latest figures for the 3-month period ending June 2012.

Microsoft is sitting in second-to-last place at 3.8% of the market, which is out of an estimated 234 million smartphone users in the United States. While the chart above shows that the dip is only -0.1 points, that's between the three-month time period of March and June. If we were to compare it to May, Microsoft actually fell from 4.0% which is a -0.2 drop month-to-month. Percentages are always a little tricky though, especially because comScore's values are relative to the rest of the market. So if more people are buying smartphones, the numbers for the smaller players who aren't growing at the same rate as bigger competitors tend to shrink.

Still, it's disappointing to see that the bleeding really hasn't stopped after all and that Windows Phone 8 could need an extra boost of support to get any forward momentum going again. Thankfully, the phones we know about from HTC and Samsung so far are shaping up to be exciting products so we can still hope for the best.
