A few choices:
Blackberry Storm (if unlocked, can be used with any network because it’s both CDMA and GSMtakes Sim)
iPhone 3G
HTC HD2
Are they good? Yes. But, they require extreme care if you’re as conscious about its appearance as some of us. Not to mention they’re more fragile than your old cell phones, so dropping one would probably end in immediate death. (Invest in an extended warranty.)
