The best part of a global show like Mobile World Congress is that you get tuned in to how the rest of the world lives. When it comes to mobile phones, most Americans expect to carry one phone and sometimes will carry a Blackberry for e-mail and regular handset for phone calls. After watching one person after another pulling out a never ending variety of handsets over the course of the day, I started polling people as to how many handsets they were carrying.

The typical person from EMEA or Asia was carrying a minimum of three phones. One person pulled out four, jokingly said (I think) that he had one for each wife. The typical explanation was a Blackberry for e-mail, an iPhone for applications, and then a Nokia or three depending on countries (and marital status). This could explain the relative health of the mobile phone space.

As for iPhones, universally, they were jail broken (manually “adjusted” to allow it to used on any mobile carrier’s network). People looked at my AT&T iPhone with a mixture of pity and disgust usually reserved for naive children. Invariably, they would show me a great application, then shake their head and say that I can’t get it because my phone was “on network.”

Social networking on mobile phones seemed to be in the early adopter phase. While I saw plenty of tweets and Facebook updates, I did not see many people using their phones to deliver them.

As the next major wireless show, CTIA, starts in less than a week, we will report back if there is a major difference in phone habits from the U.S. based attendees in Las Vegas.
