Per the title, I have a Mobileme account, which is working fine. I have held off on making the jump to icloud due to all of the confusion about my mm id versus my store id. If I push the button and send everything to icloud, and it is NOT working correctly, can I delete the icloud accounts on my MBP ipad2 and iphone, and go back into Mobileme (at least until they kill it next summer), or is this a "no going back" kind of transfer?
