Some time ago Sony Ericsson said they would learn from the development of their GreenHeart concept mobile phone in future devices, and now according to a report on cellpassion, Sony Ericsson has stated they will announce mobile handsets on the 4th of June.

This means that Sony Ericsson will be announcing a few greener handsets on the 4th which will probably have charger that waste very little power, eco-friendly housing, electronic manuals, super efficient green packaging and no doubt other tech.

The announcement is expected at 1:00PM UK time via webcast on Thursday when we will find out what Sony Ericsson has in store.
