Difference between HSDPA and HSUPA?

What is the use of having a phone with HSUPA instead of HSDPA? Please, don't give me deffinitions of wikipedia or whatever. I just don't understand why a phone would prefer higher 'uploading' to satellites then 'downloading', since most uploads are very small compared to how much a phone downloads. Also, do HSDPA enabled phones perform uploads using a different 'system'? I'm a little confused here. Just please, if you do not know how to explain the question yourself, don't try. I've read the wikipedia pages, I know what they stand for. I jsut don't quite understand how it works :) Thanks for any help

  1. They are both pretty much the same thing. The only difference is HSUPA is newer and faster. HSUPA is suppose to have a slightly higher average download speed when doing tasks on the internet. However, the key improvement is upload speeds are faster at max speeds and at average. Not sure how much faster all these speeds are. The faster upload speed is suppose to be nicer for people who have phones with camera for video chatting, where you are sending data to another person(you are also receiving data from the other person). You are also uploading files when sending a picture message, video message or music message.
