The background, 5 icon dock, and other tweaks that appear in the images above are not available on a stock iPhone/iPod Touch.

These are available to users who Jailbreak (hack) their devices:

Jailbreaking is frowned upon by Apple, and could void your warranty. Attempt at your own peril.

My mix works on my phone with absolutely no errors or annoyances (thankfully). This is what I did to set up:

Under Settings > Mail, Contacts, Calendars
Select Add Account > * Here you will be prompted with a menu that has Gmail, Yahoo, etc. Select ‘Other’.

Choose Add Mail Account, then enter your contact info for your mix account. After it checks your info, select IMAP at the top so that it is highlighted in blue.

Now, for the section IMAP Account Information:
Name: Enter your full name.
Address: Enter your full mix address.
(Description will fill in itself)

For the section called Incoming Mail Server:
Host Name: mix.wvu.edu
User Name: type your mix username
Password: type your mix password

For Outgoing Mail Server:
SMTP: exsmtp.systems.wvu.edu

After you Save all of this information, it takes about 5 minutes to process… Just wait until it finishes, it will work, I promise

Finally, after your email is set up, go back into Settings > Mail, Contacts, Calendars
Click your mix account
Click SMTP
Under Other SMTP Servers, Turn ON AT&T SMTP Server
This will help with sending emails.

That should be it! Good Luck.
