I’ve spent about 22 of the last 48 hours working on some last-minute updates for a website I’ve been building since last year; this included pulling some Flash out of my butt, making a lot of sitewide updates, and a few hurried conference calls with folks in California.

The company’s name is TalkPlus, and the deal is that they add services to your existing mobile phone. If your phone has a Maryland area code and you’d like to have a Los Angeles number for your presence there, TalkPlus can give that to you. The service also includes a bunch of features not available with some standard mobile acounts-the ability to screen calls by incoming number, voicemail that can go to your email account, multiple outbound IDs (you could spoof your own caller ID, essentially) and a few other goodies.

They’ve just opened a public beta, and for a limited time you can try the service out for free. I’m not sure what numbers they have available right now, but if you spend a lot of time on the road, have multiple offices, are dating and wish to keep your actual number private, or just like fooling around with technology, check it out.
