We're switching to T-Mobile in December, and I was planning on keeping my w810i that I use on Suckgular since it's unlocked, but the Pearl caught my eye and now I'm really considering one. Few questions: 1. How well does it work with Macs? Can I sync iCal to it, and does OSX recognize it when its plugged into a USB port? I'm not really concerned with syncing contacts or e-mails, just calendars. 2. How does e-mail work? I've 3 accounts, GMail, an IMAP account, and an IMAP/Exchange account (either one of the 2 can be used for that 3rd account). GMail, I'm content with using their WAP site. But the other accounts, do I just add those accounts to the phone and I can check them just like any other email client on a computer? Whats e-mail push that I hear about? 3. Can I tether it with my Mac to use it as an EDGE modem? If so, what sort of speeds can I realistically expect? 4. Are there any MSN and AIM clients for the Pearl that use data? I know some use SMS to send and receive messages which isn't cheap, but if I get the Pearl, I'm getting the $20/month data plan and would like to use data for IMing since it won't cost extra Thanks.
