Version 2.2 of Google's Android smartphone platform will be released in May, with the Google Nexus One reportedly in line to be the first phone to get the update.
Rumours of the imminent appearance of the new iteration of the platform surfaced after fan site Android and Me logged mobiles using Android 2.2 surfing the internet.
This almost certainly indicates that Google is in the process of testing Android 2.2 in the run-up to an official launch.
The Google developer conference, which is being held in San Francisco in late May, is being touted as the event at which Android 2.2 will arrive.
Observers are also suggesting that the Nexus One will probably be the first smartphone to benefit from an Android 2.2 upgrade.
This would definitely give it the edge it needs over the near-identical HTC Desire in the software department, making the Sense interface a little less of a talking point.
Android 2.1 will be a relatively new platform to most users, with the HTC Desire and its cheaper sibling the Legend only recently bringing it to the UK.
Meanwhile, many will still be using Android 1.6, which is behind the workings of the Sony Ericsson Xperia X10.
