I am planning to get the iPhone 3G, but I have 2 questions: (1) Will I be able to sync the iPhone to my Mac for all the iTunes stuff (music, podcasts, videos) while syncing it to my PC at work for my Microsoft calendar and contacts? (even though my firm is not supporting push email for Exchange at this time). (2) I saw someone suggest that since my firm is not supporting Exchange push email, a solution would be to set my firm email to be automatically forwarded to my .mac email account. I know how to do this and it seems to work well, but is there a way to set my .mac email preferences so that when I respond from my iPhone it looks like it is coming from my firm email address rather than from my .mac email address? It doesn't seem to give me this option. Any help would be appreciated. Thanks.
