We’re here at Mobile World Congress 2011 and we’ve got our hands on a ViewSonic v350 Android 2.2 Froyo smartphone. This phone has a brand new feature – dual SIM cards. This feature is possible with Android stitching the two together, making it possible for you to use one for business, one for personal, or perhaps if you’re a traveler, you can switch between the two SIMs on the fly. As the title of this post suggests, we’re pretty sure this is the very first dual-SIM Android smartphone in the world.

The ViewSonic v350 works with Android 2.2 Froyo, no word on upgrades yet but if the ViewPad 4 is any indication, Gingerbread is more than likely on the way. It weighs in at 125 g, has a 5 megapixel camera on the back, and has a 3.5 inch screen with 480 x 320 pixel resolution. One of the really cool features this phone comes with (other than the dual-SIM) is Smart Switch. This is a feature that’s going to be essentially standard from what we can tell on all Android products coming out this wave from ViewSonic.

The v350 they’ve reminded us several times is Google Certified, meaning it’s not second class, essentially, and from what we’ve seen having held the device in our hands, flipping back and forth a bit, it’s going to be a big contender in the market very soon regardless of its Android 2.2 Froyo state. This dual-SIM situation is going to be a thing of the future, at least until they can figure out how to quit using SIMs altogether – believe it!

Have a look at our exclusive photos of the ViewSonic v350 below:

NOTE the following (above and below) – you can see here how the v350 has both SIM cards underneath its battery on back. One connects via a swinging metal clasp like you’ve seen in such phones as the G2, and the other flatly in the upper right. One of the most evident places you can see the dual-SIM use in the phone is on the call screen, from whens you can call from either SIM – two different call buttons!
