iMessage with a twist
wouldn't it be great if instead of iMessage looking like sms with read reciepts if it was a stand alone messaging service much like bbm/live profile/whatsapp/ping/etc. where each phone was given a unique id number that you could pass out to others instead of your phone number or email.
Honestly thats the one thing i miss about my blackberry, being able to talk to people all around the world without giving out my number until you knew if they were someone you wanted to have it. With the unique id number (for blackberry it was the pin number) you were able to talk to people day and night from all over the globe, without international texting fees or phone calls in the middle of the night from creepy stalker like people.
i think that is what iMessage really should be instead of just another way of smsing with people who have other apple products.
