Please help. I can't send iMessage from my phone number. Whenever I try to send one, the sender is my email address. I checked under setting, it keeps saying that it's "waiting for activation". Under RECEIVE AT, it's only showing my email address. No phone number. I have tried all kind of suggestions that I can find online, but nothing works so far. I lost count on how many times I do a restore. Also, when I connect my iPhone to iTunes, my phone number doesn't appear on iTunes. It's listed as n/a. The phone number works fine, btw. I can make & receive a call, send text, browse internet. I just can't send an iMessage (and facetime) using my phone number. This is a brand new iPhone 4S with iOS 5.1. (I upgraded to 5.1 when I first synced it). I had no problem with my old 4S and this new one is bugging me Any input is greatly appreciated!
