Q: I have updated my iphone to ios6. Since then i am not able to backup my data to iCloud. While backing up an error occurs says the backup could not be completed.

What worked for me was to:

1. Go to "Settings" then "iCloud"

2. Turn off everything that was turned on (mail, contacts, calendars, etc.) but leaving the data on my phone.

3. Go to Storage & Backup, turn off iCloud Backup

4. Go back to iCloud (back 1 page), turn everything that I wanted to back up, on.

5. Turn iCloud Backup on, then pushed Back Up Now (making sure phone was plugged in, wifi picking up with all bars, & locked phone).

When I checked my phone after about a minute, it was working.

This worked on my phone, but can't get it to work on hubby's, but I haven't had great wifi connection with his when I've tried. I'll try again this evening and update then.

Hope this helps.

I can not update icloud on my os in widows 7.
