BARCELONA, Spain -- One of the interesting things about attending an international event like 3GSM is you get to see what services may be in America's future.

One was 3united Mobile Solutions, a company based in Vienna, Austria, that VeriSign purchased Monday for 55 million euros. 3united, founded in 1999, gave a short presentation to media and analysts today to explain what it did (and possibly justify that large of a price tag).

It said in a recent promotion with a Vienna radio station, it helped sell 10 percent of the tickets for a Britney Spears concert by mobile phone. But that's not all. After the concert, it sent a text message to all the mobile ticket holders offering Britney Spears ringtones and other content. The promotion worked, and 85 percent of those who received the message, bought something.
