I use two languages in my SureType, English and Portuguese. I only need American English, but British English is always present in the switch menu and makes me kind of hesitate a little when I'm switching because the trackball doesn't make for a very accurate mechanism. I wish I could remove English UK altogether, but I haven't been able to. Is that possible?

Do you have a Setup Wizard icon on your device? If so, go thru the setup wizard and you can remove the languages you don't want.

Of course I tried that. The only options for removal are English (cannot be selected), Portuguese and Portuguese BR. English is mandatory, so I select Portuguese BR. I still get both English US and UK, and both Portuguese PT and BR. At least Portuguese PT doesn't show up in the SureType language switch.
