If purple was Winter '07, lime green is Spring '08. By which I mean that there is a Sony Ericsson being launched in that colour, rather than any kind of fashion prediction.
This is the Sony Ericsson K660i, which is getting a green paint job exclusively at 3. The K660i is HSDPA enabled, and it's all about getting you using internet on the go. You can video blog and upload stuff there and then, get RSS feeds delivered to the 'desktop' of your phone, you can even browse the internet pages horizontally, making full use of the screen.
Check it out here at 3from Monday.
