Eyebrows were raised in the smartphone business today when, following their unveiling of the Windows 7 Phone platform at MWC2010 recently, Microsoft launched an Android app. "Tag" is a barcode reading app which they also launched on the iPhone, J2ME, Blackberry and Symbian S60 handsets. On the face of it this is hardly revolutionary, but the trend to have a single app for all popular platforms may be what's behind this move. The barcodes Tag can recognise though are different - they are color, and so hold much more data than the usual black and white (even 2D) ones.

The first Nexus One update will start rolling out any time soon. This contains various fixes and enhancements including:

• 3G stability improvements
• Multitouch
• Google Maps V 3.4
• Google Goggles

There have been various glitches reported with the Nexus One since its launch - some of which are not mentioned in this update, such as the screen losing its touch and car bluetooth problems, but perhaps the worst was 3G being described as "spotty". This was noticeable where the signal strength fluctuated wildly - even when in a desk next to a G1 which held a rock steady 3 bars, for example.
