LG CU400 / CU405
UMTS or HSDPA
HSDPA is an upgraded, faster version of UMTS. Therefore, since the CU400 does not have HSDPA, the data connection is much slower than on an phone with HSDPA.

HSDPA IS UMTS. ITS ALL THE SAME THING
No, it is not! That's like saying that GSM and GPRS is the same thing. Educated yourself before you argue with Rich

Go to http://en.wikipedia.org/wiki/HSDPA
You can have UMTS without HSDPA, but not vice-versa.
