IPhone killer? Unlikely. But if this report is true from Spanish blog MuyComputer, Microsoft is officially taking a stab at it.

The report says that the rumors are true and that in Barcelona this month Microsoft will introduce the world to its Zune Phone at Mobile World Congress.

Our source, Gizmodo, notes that the blog is “100%” sure that it will be announced and is also ture that MuyComputor is a reliable, credible source.

The Zune Phone will use the Tegra platform that Microsoft has already partnered with for their Zune high definition device.  According to reports, will a 480 x 272 screen (wha?), HDMI video out, weigh around 2.45 ounces (70 grams), and will use Windows Mobile 7.

Neowin reported last month that Microsoft sources confirmed that there was no “Zune Phone”. According to Neowin, the device will be running Zune software but Danger branded, not a “Zune Phone” so to speak.
