123SPOOF.com has released  BlackBerry Beta application that allows free caller ID spoofing! Although free, you must listen to a nine second advertisement unless you are using the paid version. Free is always awesome though!

From the description:

123SPOOF Mobile is a revolutionary Blackberry application that gives you COMPLETE control over your phone calls, empowering you to change Caller ID, disguise your voice, record your calls, and more! All this is combined with seamless BlackBerry integration.

Best of all, 123SPOOF Mobile now lets you make unlimited calls for FREE. You don’t even have to sign up or enter any personal information to take advantage of this amazing offer! What’s the catch? When making free calls, 123SPOOF Mobile requires that you listen to a short, nine second advertisement. Users who want to take full advantage of 123SPOOF Mobile without ads can sign up for an account online or inside the app.

Here are a few of the major features that you will not find anywhere else or all in one place:

• Go straight to someone’s Voicemail. Don’t feel like talking to some people? Just leave em’ a message! Their phone never rings, but still shows a missed call from your spoofed Caller ID!
• Record your calls and replay them straight from your phone. 123SPOOF Mobile also integrates with your address book
• Spoof internationally
• Local access numbers in 40+ countries
• Spoof DIRECTLY from the app! No call-back needed!
• Best real-time Voice Changer

…

Pretty cool! Just don’t abuse this application and end up getting sued .
