Whenever I try and activate iMessage or facetime on my iPhone 5 all I get is the error, "Could not sigh in, please check your network connection and try again." The error doesn't happen right away it takes about 15-30 seconds then seems like it times out. I tried to activate on both wi-fi and data connection to no avail. I've read a few other areas where people have had these problems curious if anyone has as well and any fixes. Thanks!
