Technically HSDPA is same as 3G. The only difference is that there are improvement in software layers for HSDPA.

There are two technologies for 4G - LTE and Wimax.
LTE (Long Term Evolution) developed by Ericsson is capable of 155Mbps maximum and is what most of the networks are moving to.
WiMax is a modified version of wifi which can cover a distance up to 50 miles, but is unlikely to gain much traction. It will only prove to be a distraction from LTE much as CDMA was a distraction from GSM/UMTS/WCDMA.
You cannot connect an existing wifi device with WiMax to my knowledge.

W995 is the only SE phone in the market with 7.2mbps HSDPA and 2.0mbps HSUPA. With the latest firmware, my 3G signal will switch to HSDPA automatically everytime I connect to the internet which is great, before this it used to pick up any signal that was strongest. It downloads really fast, maximum I had was 500kb per sec but usually it's around 100-200kb depending on location and network provider, but I find the HSUPA to be especially useful with all the stuff we upload on the net these days. Couldn't upload jack with my 3G capable-P990 as it was too slow to the point that it prompts error messages from websites most of the time.
Downloading was OK but only went up to 40kb per sec, max.

3G is capable up to 384Kbps downlink speeds, 3.5G/HSDPA up to 7.2Mbps the maximum theoretical rate is 14.4 Mbps. WiMax is still very slow in its deployment though it has been roll out...
i've tried WiMax connection and it has a very very low signal dropped, covers a wider area, poor in downloading, not that good in uploading, take ages to load webpages and sometimes no connection activity

21Mbps HSDPA is available in Australia since February and VodafoneNZ is releasing a 21Mbps HSDPA upgrade in Auckland this month.
AFAIK, WiMax is still in the development stage and will be rolled out first in the US.

the only way to have either is to be in a NETWORK that supports it. I recommend talking to each about if their service support HSDPA or 3G, also make sure that your phone can support either HSDPA or 3G
