The reason why you cant enter the codes most likely is because you probably have a different dialer skin loaded in your phone, like inesoft, or some custom roms dont work with the## codes. If you hit ##data#, or any other codes like listed above, thats the problem. If you go to the dialer, hit menu, options,services,internet, Then hit start IOTA. If you have a custom rom the internet option may not be there. You would need the IOTA cab file to get that back. If you need it, let me know.

Here are some .cabs
IOTA cab will give you the internet settings in the phone options as I explained above if they not there already. Then you will be able to update your IOTA.

Dcd Sprint cab will set your internet to point to the correct number#777 in your connection settings.

Sprint update profile and prl cab will put the update option back in start/settings/system folder
