the thing i don't like about iMessage is that you can't choose to send a sms over iMessage.
What if I wanna send a text instead?? I can't anymore. It'll always shoose iMessage by default.
I wish they would make a list of all the contacts of people who have iMessage.
iClouds and wifi-sync to iTunes is awesome.
