TalkPlus's new Multi Line service is in the beta stage, and they've made some useful features such as:

• Add a new number to your phone, complete with voicemail - free
• Get $10 in free credits, for making calls or adding an additional line
• Place and receive calls on any of your new lines
• Conduct conference calls for up to 10 people
• View calling history for each number
• Easily access your account information using the online Contact Center

Available as a 30-day trial, for Palm, Symbian, and Blackberry smartphones. Basically, the name "Multi Line" is pretty self-explanatory, letting you maintain different international numbers on the same phone. Meaning you can keep contact groups like business associates, fan club members, girlfriends, and plain 'ol friends separate from each other, and control who can contact you at any given time.

Thanks to MyTreo.net for the heads-up.
