How long does it take for iMessage to deactivate?
I got a new phone (android platform) and traded in my iphone 4. As I've seen many others post about I've encountered that common problem with not receiving messages sent by my friends with iphones. (Although it seems to only be those with ios 7.) I went and unregistered my old phone as suggested in other posts. My question is this, how long will it take for it to actually deactivate after I unregister my phone? Does anyone know? Thanks in advance!
