Plugged my iphone 3gs into my desktop this morning to update and it was connected for almost 3 1/2 hours. Very confused about messages I received about updating, backing up, restoring, ICloud, Wifi. Didn't know if I should allow I-Cloud or Wifi, as I really don't know what i-cloud is. I don't know what the heck was going on. Is it normal for it to take this long to update software. Hope I didn't mess anything up on it. Thoughts/comments appreciated. Thanks.
