Sony Ericsson

hello there...i was hoping i could get your opinion on a few questions i have. i have been debating on the fuze,iphone 3g, and the sony ericsson x1.
you mentioned the fuze does video streaming...how is that different from video call? the sony has dual cameras for video call where as the fuze has just one main camera. i know skype just came out with a panel for the sony but im not sure if you can make video calls through it. no one seems to know wether or not it can be done. if you are not familiar skype is a voip. just like webcam for your home computer. im looking to hopefully find a phone where i can do video chat mobile. if i was reading correctly the fuze does live video but will it work through skype for their webcam? skype is free so im hoping to fid someone who has installed it to tell me if it works or not. what is your take on the fuze vs. the sony? i know apple is supposively launching a new iphone come june but no specs yet. any advice would be greatly appreciated.
thank you
