[SOLVED] How does iMessage work ?

Just curious here.

How does iMessage work ? When I want to send an SMS, does it first send
it to Apple to find out if that telephone number is a destination known
to Apple and if not, it then sends it via the mobile network's SMS ?

So this would mean that Apple keeps tracks of every iPhone user in the
world who is currently "on-line" ?


Is there a way to know while typing the SMS whether it will be sent via
iMessage or via SMS ?

If the To bubble is green, it is going out SMS. Blue: iMessage.

If you have iMessage enabled, as soon as you enter an address
or phone number to which you want to route a message, Messages
contacts Apple and sees if that address is recognized. If so,
Messages turns from green to blue to let you know that the
message will go out over iMessage.

Nope. If you don't have iMessage in front, then any message
that comes to you over it comes by push.

The color. And the light gray text in the box in which you type
the message will say "iMessage".
