find my iphone

i have just done the 3.0 upgrade on my iphone3g.

everything seems ok.

but when i try to turn on 'find my iphone' i select 'allow' but it doesnt turn it on.

i have push turned on so it cant be that, can anyone help?

Do you have MobileMe? If you do, is the account attached to your phone?

MobileMe is required for the find my phone and remote wipe features, so if you are not a subscriber, it will not function.

yes got mobile me,

i went to my local apple store today and even the genius bar have no idea what the problem is, i will keep searching the web !!

It's unfortunate that the Apple Genius was unable to assist you. Is your phone still under warranty? If it is you should insist that they either repair it or replace it.

Barring that, I would suggest restoring your iPhone through iTunes. Once the restore is complete, DO NOT restore a backup of your phone as the problems you are having may reoccur.

After you have done that, your phone will need to be set up again with all of your accounts and stuff. Hopefully that will fix your issue.
