Good to hear from you. You’ll find a whole bunch of iPad enthusiasts in this Forum who are only too willing to help other iPad owners and to hear of their experiences. Don’t be afraid to post any questions you may have or use the ‘Search’ button near the top of the Forum web page. I usually find I discover one new interesting and useful piece of information about my iPad every day - and often not even what I was looking for!!
I saw your question about being unable to change your email settings. Rather than changing the existing settings could you delete your existing accounts and simply set up new ones? Sorry if I've misunderstood your question. If there are other issues - i.e. you can't even enter new account information - try 'power recycling' the iPad, turning it completely off by holding down the Power button for a couple of seconds, accepting the 'slider control' and, when the screen has gone completely blank, hold the Power button down again for a couple of seconds. It takes about 10 seconds for it to power back up again so have patience!! Hope this helps but if there's still a problem, don't hesitate to get back in touch.
Hope to hear from you soon with your thoughts about the iPad.
Have fun and enjoy your iPad
