The Samsung Galaxy S II’s Jelly Bean upgrade has finally begun its rollout in Spain today, reaching international handsets with the GT-I9100 model number. In addition to new Jelly Bean features like Google Now and Project Butter, the software brings Samsung’s latest “TouchWiz Nature UX,” which has been gracing the Korean company’s latest devices since the Galaxy S III launched in May 2012.

Although Mozilla has stated that it won’t produce hardware for its upcoming Firefox OS, the company has teamed up with Spanish startup Geeksphone to offer a pair of developer devices. Called Keon and Peak, the devices are designed to provide developers with the opportunity to “tap the future of mobile” and get to grips with the platform that will soon be trying to steal marketshare from Android and iOS.

Samsung has begun rolling out Android 4.1 Jelly Bean to two of its tablet in the United States. The Galaxy Tab 2 10.1 and the Galaxy Tab 2 7.0 both began receiving the upgrade over the weekend, following its debut on European devices. As you’d expect, this software comes with a whole host of new features and improvements.

Google has begun rolling out its latest Android 4.2.2 Jelly Bean upgrade to the LG Nexus 4. The software is currently reaching handsets located in Brazil and Malaysia, according to reports, but it’s likely it will also appear in other countries relatively quickly. Unlike Android updates for third-party handsets, Google’s don’t have to go through carrier testing.

Motorola has confirmed that its Android 4.1.2 upgrade for the Droid RAZR and Droid RAZR MAXX will begin its official rollout during the first quarter of 2013. The software first made an appearance on a small number of handsets back in late December, but Motorola quickly ended its rollout without explanation. Now it won’t be long before it’s moving again.
