The latest in Sony Ericsson’s GreenHeart series of mobile phone handsets has been announced by the company.

To be known as the “Cedar” handset, this latest environmentally friendly phone is candy-bar style, is made from recycled plastic, has a low power consumption charger and will be supplied to consumers in ‘green’packaging with no paper instruction manuals, all for the good of the planet. Functionality isn’t overly compromised by it’s environmentally friendly aim though, with the handset offering a 2.2 inch screen, a 2 megapixel camera, 3G HSDPA for high speed internet access and a widget manager which enables easy social networking access.

Sony Ericsson is having a real tough time with their security. Details about upcoming handsets have been leaked recently and this time it’s the Sony Ericsson “Julie”.

The Julie is reportedly a Windows Phone 7 device. It is rumored to look somewhat like the Xperia X10. The phone will sport a QWERTY keypad and is likely to support multi touch gestures. It will mostly be powered by a 1GHz processor and rumor is that it will feature a 4″ multi touch capable display too, something the Xperia X10 range is sadly lacking.

What look to be ‘Official’ photos have emerged of the Sony Ericsson Xperia X8, also known as Shakira, over on the se-nse blog.

Although exact specifications of the newest incarnation of Sony Ericsson smartphones haven’t been released yet, it appears that the Xperia X8 is, as expected, a cross between the full sized Xperia X10 and the smaller X10 Mini, sitting in the middle of those sized phones. It has been noted that there doesnt seem to be any flash for the camera on the X8 which would be disappointing but again, until specs are released by Sony Ericsson we can’t confirm that.

The Sony Ericsson Xperia X10 Mini has now been released in the UK on most networks. Both Vodafone and O2 have the X10 Mini in stock, although it’s unclear which color they are stocking and sending. Orange on the other hand, also have the handset in stock but, they have an exclusive deal with Sony Ericsson, like the did for the Xperia X10. Orange were able to gain exclusive rights to the white model of the X10, while the other networks just had the black model and this time, Orange are the only UK sellers of the Lime Green Xperia X10 Mini.

Sony Ericsson is developing the next phone in their eco-friendly Greenheart series. The phone is codenamed Sony Ericsson Hong. It is expected to be a classic stick phone and have a design similar to that of Sony Ericsson Elm. The specifications of te phone are not yet known.

The Hong is the seventh phone in the Greenheart series. The Greenheart range of phones are  eco-friendly. They are manufactured from materials which do not harm the environment. The phones carry an in-phone manual rather a paper manual. It is made from re-cycled plastics and uses an energy efficient display. All these features reduce Carbon-di-oxide emissions by 15%.

Sony Ericsson is developing a new type of touchscreen which detects the finger’s pressure on the Z axis in addition to the X and Y position on the screen.

Sony Computer Science Laboratories (Sony CSL) Inc. gave a live demonstration of the new panel at an open house event. The panel was fitted into a small device for the demonstration. The icons moved faster or slower depending on how much pressure was exerted on the screen.

Sony is aiming to reduce power usage and cut down manufacturing costs before making it available for mobile devices. According to Sony, “commercialization is not far of”, and the technology could make it to mobile devices really soon.
