I think that when IOS users activate their iMessaging accounts, their emails or phone numbers are added to an apple iMessaging database. It is in this way that your machine knows whether the person’s email or number you are trying to contact is in the database or not. all your contacts are identified as iMessaging contacts r not. This is the only way I can think of. Cheers,

From: Arnold Schmidt Sent: Tuesday, February 05, 2013 8:05 PM To: viphone@googlegroups.com Subject: IMessage Versus Text Message Question I understand that an iMessage can have an unlimited number of characters, but only can be used between Apple devices. A text message allegedly only can have 160 characters. If I have iMessage turned on,how does my phone know whether the recipient is using an Apple device, or not, to which it is sending my iMessage? And if I send an iMessage to a non Apple device, I guess it is delivered as a regular text message. Does it just cut off after 160 characters? I do intend to buy the new book, published by National Braille Press, about iMessaging. Thanks for any information.
