SkyFire is getting ready to roll with its rich mobile browser. Last May, the company (finally) released its Symbian program after a long beta trial and announced that a BlackBerry version was in the works.

Earlier this Summer they hired former Travelocity executive Jeffrey Glueck to lead the company into the next phase. Now a regulatory filing reveals the startup has raised a Series C closed off its earlier Series B round of funding with an extra $5 million, reports peHUB.

There were no new investors cited in the filing, so it’s safe to assume this was a follow-up round from SkyFire’s existing investors Lightspeed Venture Partners, Matrix Partners and Trinity Ventures, who had previously invested $17.8 million in the mobile browser maker. The total amount of funding raised by the company now reaches a healthy $22.8 million.

Skyfire is free and the only mobile browser that currently supports Flash, Silverlight, and a number of other technologies generally reserved for desktop browsers. The software runs on Windows Mobile (smartphones and PPC) and Nokia N and E Series (Symbian S60, 3rd Edition) phones.
