J.A and Girdaman,
I appreciate the responses. I had wiped my Gen 3 IPad and gave it to my wife after I purchased my Gen 4 model. The first thing I noticed was that the "Send" and "Trash" boxes were missing under the list of boxes listed in your picture on my wife's Gen 3 after i resynced it from iTunes. After she started using her mail and created a message and sent it, the "Sent" box appeared. Interestingly, after she erased a message the "Trash" box appeared. So I'm guessing these boxes automatically appeared but only first use. My wife did have a first Gen iPad which was full of "Sent" messages which I had previously synced with iTunes, the 3rd Gen had been wiped clean and then synced with the data from the first Gen backup. I'm assuming that the sent messages that were on her first Gen got lost in the process.
Again, thanks for your responses,
Pat Canady
