HTC TouchFlo technology is innovative & successful. It have open Windows Mobile user eyes for its attractive & unfriendly touch interface. i can say it 1st of it kind in the industry which can compete with Iphone interface 
However this innovative interface only available for HTC own product line… so sad 
Until nowadays Some expert have find a success way to install it on most of the Window Mobile 6 Phone
Previous version is not stable untill this latest release before this got ppl use Flash for Touchflo (this is not real Touchflow, anyway)
Do sit down & enjoy TouchFlo in your PDA phone today , happy install
