After a diet, the new Opera Mobile 12.1 for Android is ready to show off its new binary in the Google Play store.

Despite being tailor made for four different chipsets, ARM v5 and v7, MIPS and X86, the Opera Mobile 12.1 browser remains sleek since you only get the version suited for the chipset in your Android mobile or tablet.

Opera Mobile is a full-featured sibling of the data-saving Opera Mini, a browser essential for anyone on a slow network, or in need of compression to save data. Opera Mobile 12.1 features Opera Turbo technology, one click turns on the compression capability - and you will use less data.

Opera Mobile's new fraud detection system tells you when a webpage has been marked as being suspicious or used for illicit activity.

In Opera Mobile 12.1, several desktop capabilities are available for your mobile and tablet devices:

- SPDY: Shortly after the introduction of SPDY on Opera 12.10 desktop beta, the HTTP improvement protocol has made it into the Opera Mobile version. Using a new and improved protocol for communicating to web servers around the world, the SPDY protocol makes fetching webpages more efficient. Twitter and Gmail are two early adopters of the SPDY protocol.
