Well maybe I was a bit premature and all the excitement got to me... I started the iOS4 update process and have been staring at a Backup progress bar that's hasn't gotten to 5% in the last 20 minutes. I'm getting a little anxious about having my phone out of commission (and being unreachable) for more then an hour in the middle of my day. If I stop the backup, I'm afraid it'll just start updating the phone - which is fine, but I wanted a complete backup of iOS3 just in case... Will a call come through the backup process? (I'm hearing email "bings" and such) In which case I'll just let it go. If I stop the process, do I have to complete the update or does it cancel?
