Blackberry is out. On the iPhone gmail and gcal webapp work prety well. iPhone's Mail.app integrates with Gmail seamlessly but Gcal requires third party software to sync -- I find BusySync on MacOS X to be the best option. There's an iPhone terminal app that kind of works but not fully featured enough to let you manage a server purely on the phone. G1 has homecourt advantage with Gmail and Gcal integration but cruddy design and a few other minor annoyances.
