Ok the first thing you should do is remove your mobile me account from your iphone and ipad.
Now when you get the warning box that mobile me cannot sync are you getting the message on your Computer or on the Ipad and Iphone?
Sorry about that to remove the account the steps below should work on both the iphone and ipad.
From the home screen, tap Settings > Mail, Contacts, Calendars, and then tap your MobileMe account. Tap Delete Account. (If prompted to do so, choose "Delete from My iPhone" (or iPad/iPod touch). Restart your device. After it restarts, on the Mail, Contacts, and Calendars screen, tap Add Account > MobileMe, and set up your account again.
As you said "I've already told you" all of my contacts are in duplicate and triplicate and so are all of my calendar entries on my IPad and IPhone. Mobile Me did this when I put it on originally. So, I don't want that to happen again. Do I need to go back and manually correct them as I did on the computer before reinstalling Mobile Me again and how do I prevent it from doing the same thing a second time. You have not answered my question yet. Please don't mention to me if you get paid or not. If you'll just help solve my problem, you'll get paid. My concern is my problem and don't tell me - "I've already told You". I've come to you for help, not lectures.
Now I need to know about my Contact Lists duplications and my Calendar duplications on my IPhone and my IPad and how to prevent it from happening again. That was my original concern and still is my concern. If you cannot help me, please give my problem to someone that can. Thanks. Carole
