Haha I don't own a single apple device. I'm just saying this isn't the end of the world. It is a fuck up, sure, but it isn't anywhere as bad as antennagate.
Seriously how do you people deal with getting a new phone number? Do you think the phone manufactures should automatically have all your friends update their contact books with your new number? The iMessage app should fail over to SMS if it thinks the other endpoint is no longer on iMessage, but there is a very obvious work around until they release the patch.
Send MMS ,Add all contacts
Dear iPhone owning friend:
I no longer am one of you. I have forsaken my iPhone, my Siri, my coolness if you will. I now have a [insert phone manufacturer]. You can no longer contact me via iMessage. Please delete my contact and re add it or otherwise inform your iPhone that I cannot be contacted via iMessage. Your phone is currently too stupid to figure it out for itself.
I sincerely apologize for any inconvenience,
Former iUser
