Research in Motion's BlackBerry 7230 (its first world compatible color BlackBerry) is reviewed in October's issue of PC Magazine. It scored 4/5 and was praised for its 64K color screen. It got knocked for slow web browsing speeds (what can you expect on a handheld?) and the lack of a speaker phone.
You can buy the BlackBerry 7230 from T-Mobile in the US and in Europe [more on availability].
