I've always been a fan of using my cell phone to stay organized and recently found a free cell phone service that was created to help you do just that. Qipit allows you to copy documents and handwritten notes with your camera phone or digital camera to store, fax, email, or publish online.
The service turns notes into digital copies (PDFs), allows you to email or fax digital copies via email, and helps store all of your paper documents and notes as digital documents for easy archiving and sharing. It aims to be a "portable scanner, mobile copier, and a mobile fax machine, all in one." You could technically do all of the things it does without the service, but the ability to create "crisp, clear, digital copies" partnered with the fact that it's free and will archive everything in one place is a plus.

How does it work? You take a picture of your notes or document with your camera phone or digital camera, send it to qipit as a multimedia message (MMS) from your camera phone, email, or your qipit account and qipit turns your photo into a PDF or JPEG, which you can store or send to an email or fax number from your cell phone as a multimedia message (MMS) or mobile email.
