I bought it in September 07. I upgraded it to Windows Mobile 6 a month
ago. When it is sitting there idle a "3G" icon is displayed. When it
connects to the net the symbols changes to indicate a connection. When
data is flowing in either direction it changes to an "H" to indicate an
"HSDPA" connection.

Generally this occurs when either browsing, receiving emails or sending or
receiving MMSes. An SMS transmission or reception doesn't change the
symbol at all.
