Recycling an unused mobile phone is a great idea. Some great resources include web sites like Recycle My Cell Phone, Recycle for Breast Cancer and Charitable Recycling. By recycling, you are protecting the environment (the phone won’t end up in a landfill), plus you have an opportunity to support a charity of your choice. Cell phone recycle programs usually provide a checklist of steps to take before donating an old mobile phone, including disconnecting your service and manually erasing your address book.
