why am i having so much trouble trying to log into my icloud account. I have been trying for 2 days now on two different computers in 2 different locations. I can get to the log in screen, type in my apple id and password, then keep getting screen saying icloud showed an error connecting to server. I am very new at all this smart phone stuff and just want to check my icloud account to make sure my back ups are working and to import some photos off my phone to make some more room? Getting very frustratied, HELP am I doing something wrong?
