I'm quite close to deciding to replace my V3 RAZR, Palm T|X and 1st Gen 2GB Nano with an iPhone, but there are two things I'm wondering about first: 1) I understand that the iPhone doesn't support Bluetooth stereo headsets yet. What are the chances it will in the future? I'm not a fan of 'earbud' or wrap over the ear speaker types. If it does get implemented, would it be as simple as a firmware release, or would it require the purchase of a newer iPhone? 2) Can I 100% sync my iCal on my MB with the iPhone? I don't do any heavy-duty scheduling with it, but being able to drop the Palm would be great. Thanks!
