If you can't IM from your cell phone - or Adam's AIM BudgetBot is just too geeky for you - the Financial Aid Podcast has another method for tracking your expenses on the go with your cell phone.

Basically, using K7.net's free voicemail box (which emails you new messages) and a Gmail account, each time you spend money, leave yourself a voicemail saying something like "57 bucks at Fry's for headphones." Set up Gmail to shuttle any messages from K7 to a "personal finance" label. Back at home, use all the messages filed under that label to tally up your expenses. This method requires a lot of listening to voicemails to self, but it is easy instant capture all to one place. Thanks, Christopher!
