Re: Sorry..but,
Have to agree. It just works. They're also pretty much indestructable. Mine was in such a sorry state after falling out of top pockets down flights of stairs, falling into sinks full of washing up and just generally being abused that it became a sort of office joke. Everyone was routing for it.
It still works. The battery isn't very good, but it still works just fine.
When I was in working on a pipeline project in Turkey it literally saved my sanity. In those days, one could stream BBC radio programmes using RealPlayer, which was really great at streaming with very low bandwidth requirements. It was perfectly possible to stream radio programmes using the 6310i as a modem (using the bluetooth connection) even with the 6310i's lowly GPRS modem. Worked a treat.
Great phone. And great car kit, too!
