3G v/s 2G

3G uses a software enhancement
called High Speed Downlink
Packet Access (HSDPA), which
sends data many times faster
than current 2G networks. For
you, that translates into the
freedom to send and receive text,
graphics, audio and video
content, in 3G coverage areas.

There are currently 3Gphones
available (WCDMA) which will only
support maximum speeds of
384Kbps , In order to get the
best 3G experience we
recommend using phones which
are HSPA based .These phones
