I got my iPhone 5 back on the 16th and thought a few friends were ignoring me.. Well it turns out they do not receive my texts.. It looks like it sent and gives no indication it didn't. Both of these people are using blackberrys. And they are different models. Any advice for me to get my messages through to them?? I have googled it a few times and found posts from 09 but nothing more recent. Oh and it shows like a regular text message not an iMessage..
