SAN FRANCISCO – Google is set to unveil the latest version of its Android operating system, version 4.2 on October 29 in New York though there’s some controversy over just what the new system software is to be called.

Some observers, bloggers, etc. are saying version 4.2 is just a minor update of 4.1, and will carry the same “Jelly Bean” moniker.

Others are claiming it will be more far-reaching and will be called “Key Lime Pie”.

(Each new version of Android carries the name of a supposedly delectable substance, with the names progressing alphabetically – eg, from Cupcake to Donut, Eclair, Froyo, Gingerbread, Honeycomb and Ice Cream Sandwich.)

While key lime pie, which is made from a particular small lime also known as West Indian or Mexican lime, is little-known in Australia, it’s a delicacy served in every American diner, including the low-cost but much respected Denny’s chain.

CDN, an occasional San Francisco Denny’s patron, can confirm it’s scrumptious.

Whatever it’s called, Android 4,2 supposedly will involve a new version of the Android Gallery, and support for multiple users of a single gadget.

Google will also be showing off the first devices to run on Android 4.2, including a high-end 10-inch tablet, the Nexus 10, from Samsung Electronics, and LG Electronics’ first Nexus phone, the Nexus 4, according to CNet.

Also expected is an updated version of the Nexus 7 tablet which debuted in July.
