My upgrade to 4 went without a hitch. But I do know of one person who
did lose the contents of their phone during the upgrade.
So here is my additional information on "backing up your iphone via
iTunes":
The first thing to note is iTunes does make a backup of your phone.
But the kicker is it only holds 1 backup (it deletes previous backups
each time the backup runs).
This backup is stored in /Users/"username"/Library/Application
Support/MobileSync/Backup.
Each iPhone that you backup will create a sub directory in this
folder.
I have found that coping this backup into your documents folders
(coping, not moving) is a way to preserve the backup as valid restore
point. To do so, connect your phone, run a back-up by right-clicking
your phone under the Devices listing of iTunes, Then, move the
updated directory to your my documents, or other safe place of your
preference.
During the upgrade the first thing that it tries to do is backup your
device. Let it do the backup. If the upgrade fails most folk just
try it again. But the second attempt of the upgrade will once again
try to do the backup. This backup will backup the phone in its crappy
state, and unfortunately it will erase the valid older backup.
But never fear for you still have the preserved copy of a valid backup
in your my documents folder. You would just need to copy back the
iphone backup from your documents folder into the Library/Application
Support/MobileSync/Backup folder to do a restore form iTunes.
Other solution to the single backup file from iTunes "problem" is to
use "Time Machine". If you use time machine you can simple restore
the backup directory to a time you knew the phone was functioning and
the backup was valid. (as in a date before the upgrade)
Demo of Provisioning:
I think it could be demo-ed during our class session might take a 1/2
hour or so. I had to do it twice, but the second time did work. I
would be willing to help out as long as everyone is willing to be
patient if it goes awry!
It is rewarding to see your app run on a phone!
Thanks,
alan
