Samsung has shown off one of the first phones to support 2Mb/s HSUPA 3G upload acceleration technology.
Samsung SCH-M470

The SCH-M470 is destined - initially at least - for South Korea Telecom's HSUPA network. In addition to the ability to upload data at a rate of up to 2Mb/s, the M470 should support downloads of up to 7.2Mb/s.

Perhaps nothing to jump up and down about, especially as this is yet another Samsung that we'll probably never see, but it's nice to see the technology in a production handset.

Bear in mind that Vodafone fully supports HSUPA in its network at [current] speeds up to 1.2Mbps which is faster than anything else in the land right now. There is a place for HSUPA, especially when dealing with multimedia files.
