There is a handful of VoIP apps for Android that can make free calls over Wi-Fi and 3G, and as of Wednesday, the list grows by one.

Fring 1.0 is an all-in-one communicator that pairs support for chat services like Yahoo Messenger, Google Talk, and Twitter with voice services like Skype and SIP. Fring also offers a low-cost service for placing international calls.

In the battle of the open-source mobile platforms, developers have at least two choices: Google Android, which is open source but (relatively) closed development, or Symbian, which is open source...once it gets around to releasing the full source code.

Guess which one is winning?

Gartner expects Android to become the second-most popular mobile platform within the next few years as it continues to gobble up Symbian's declining market share.

But why?

Google might be getting ready to launch its own Android phone, which could come in early 2010, and is designed to stand toe-to-toe with the Apple iPhone, according to reports.

Speculation over a Google smartphone was first reported by Michael Arrington of TechCrunch, who said that the news was "absolutely confirmed" by a reliable source. Arrington said that the new Google branded phone, which would be sold directly and through retailers, was initially slated to be released during the holiday season but was postponed until early 2010. Subsequently, Google will be making a massive advertising push in January as it revs up for the impending launch, according to the report.

Samsung I5700 Galaxy Spica, or Galaxy Lite, if you prefer, is official as it gets. Not only is the I5700 the fastest gun in the Android crowd with its 800MHz CPU, but it's also cheaper than the original Samsung Galaxy.

The CPU is interesting because the original Galaxy ran the 528MHz Qualcomm MSM7200A processor. But with 800MHz the Spica beats even the Acer Liquid, which until now held the crown for speediest CPU in the Android world - a 768MHz Snapdragon. Liquid still has a lead in RAM - 256MB - versus the 128 of both Galaxy phones.
