If you are wondering by any chance if mobile is really booming, the buzz about 3GSM coming up in Barcelona next week will dispel your doubts. I can remember in the late 1990s when the kind of crowding and hectic networking expected at 3GSM was typical at big Internet conferences–then the dotbomb brought down the excitement. The ‘3GSM attendance tips for those that haven’t been before‘ posted on Open Gardens describes the expected energy and challenges. One very European ouch–’transit ways between halls are carpet-covered cobble-stone’–makes me a little glad I am not going. But I wish I were!!
