It looks like there is another "iPhone clone," this time by LG (note: to my knowledge LG was the first that came out with the touch screen, but Apple popularized it).
Sprint (via Samsung) released a similar version earlier, although it may need a few more months of development as the phone was crashing in front of the tech press.
LG seems to be more of a finished product, although ironically it seems to be exclusive to AT&T (just like the iPhone). Verizon and Sprint must be hating that. :-)
