iMessages completely ******'s with my OCD. As much as I try to keep the iPhone and iPad Messages synced, there is no real way to do this in a real world setting. I have the "Receive At" field on my iPhone set to my apple user ID and my phone number. It's set to my apple id on my iPad also. The "Caller ID" is set to my apple ID on both my iPhone and iPad. The problem is not on my end. THe problem is with people on the other end. For example, if I initiate a conversation with my dad, everything is in sync perfectly, including when he responds to me (since he is technically responding to my apple id, not my phone number). However, if my dad then deletes that conversation on his iPhone and then initiates a conversation using my phone number, that's where the trouble starts. I now get a separate thread on my iPhone which obviously doesn't sync to my iPad. Apple needs to fix this imo. Not sure if they would be able to link a phone number to your apple id and then convert any message sent to the phone number to your apple id. That would be great imo and allow for a seamless experience. Bottom line is, the implentation of imessage is flawed imho. Cool story bro.
