Dear all, I am considering buying an iPhone 4 in the next days/weeks. For info, I am not willing to wait September: I intend to use the phone intensively in the next months; currently I only have a small "dumb phone". There are a few things I would like to have clarified: 1) Instant messaging / chat Do I get notification of Facebook updates? New emails? New chat (Google account)? Or do I need to open an application for each to see if something arrived? Can I leave this application running? will people see me online? 2) email Can I add several email accounts? (gmail) to the mail application on the iPhone? 3) calendars On my Mac, I have my main calendars in iCal, but I also can see ("delegates") the google calendars of my colleagues. In iCal, this long list of calendars is nice to have: I can easily toggle the display, change the color, etc. Is this possible on the calendar of the iPhone? 4) Skype When at home, on my wireless, can I use Skype or Google Audio/Video chat on the iPhone? Thanks a lot! Olivier.
