What is the significance of adding an @me account to iCloud?
The only thing holding me back is that I am not sure what will happen as regards iCloud no longer being associated with my current apple ID (hotmail)
i already had a mobileme account, so i figured i'd keep it simple
i was stuck at first because, i have seperate accounts for the iTunes Store and icloud/MobileMe. I setup the phone using the mobileme/icloud email, and just went into the app store's preference and swapped the emails over.
worked a charm
