BrainCast looks promising for us. Think about if an online service that keeps all your mind dumps, and even better you could record it wherever you want with your cell phone. This is the service for you:
BrainCast is a free message and memo service that allows you to record reminders for yourself on the go, and automatically delivers them to your PC at home for later use. There is also an online organizational system for storing your messages so you can access them from anywhere. Simply add the BrainCast toll free number to your cell phone and you can use it from anywhere free of charge!
BrainCast is intended to be used as a service to help store and organize audio notes from anywhere. Anytime you think of something where you don't have a simple method of writing something down or making a note of it, like at the store, or in the car, or out at night, is an optimal time to use the service. Just call, wait for the beep, record, and it will be home and on your computer when you get there.
