Think iPhone 3G iPhone packaged in a less attractive slider phone-chassis and a much smaller 2-inch screen and you’ve got the Sony Ericsson F305 gaming phone.  The F305 is all about “fun and entertainment’ which is the heart and soul of the device.  The company targets the youth audience seeking a better gaming experience, one very similar to what they might find using a Wiimote.

The F305 uses advanced motion sensor technology where the phone, for example can follow your actions to imitate bowling or casting a fishing line.  Owners of the F305 will enjoy up to 8 hours of gameplay, take pictures with the integrated 2-megapixel camera, share photos or music with friends and family via Bluetooth or Memory Stick Micro (M2).

Bowling, Bass fishing, and Jockey are three preloaded motion games shipped with the F305. Additional motion games developed by Gameloft™ plus 50 more 2D and 3D games available for download at PlayNow.

Other features include loud stereo speakers – enhance your gaming experience or share the latest music with friends. Horizontal game play and dedicated gaming keys – play games the way you want.

The F305 with Motion Gaming will be available in Polar White and Mystic Black in selected markets from Q3 2008. It will be a Quad-Band EDGE phone supporting 850, 900, 1800 and 1900 frequency bands.

So is the F305 worthy of a spot in your pant pocket?  At the end of the day only you can determine that.  However, according to Kim Poh Liaw, or editor of SlashPhone, the F305 is a magnet for fingerprints and smudges.  During his hands-on, there were numerous times where the darn thing nearly flew out of his hands; Sony Ericsson should have added a strap of some sort (similar to the Wiimote).  What makes it even worse is the lanyard hole sits at the top, instead of at the bottom, which “we” could to strap the phone down.

To start Bass Fishing, simply swing the F305 in a wide arc motion to “cast” the line.  During the game play, it’s back to the ordinary buttons and the Motion Gaming was only activated when you start to reel in your catch — he noted that it really required a lot of shaking of the phone.  Kim Poh’s biggest complaint was the minuscule 2-inch display — which is super-tiny for a game-centric device.  On the plus side, the rear stereo speakers are vibrant and loud, which makes up for the lackluster-262,144 color display.

I asked Kim Poh if he recommended the F305, and was told “the F305 is going to be a hard sell for Sony Ericsson, considering the iPhone 3G is weeks away – selling at $199/$299 with similar Motion Gaming features and more.”
