A computer works on binary code or computer language, 1 and 0, like if I want the letter 'a' then the code is 1. So if there is an integer error, that means the binary code was not working and thus the computer(iPhone or iPod) cannot read what you posted and thus It cannot be sent.
Apoc Shhhhhhhh. So...Would it be possible to type in only numbers and for the computer to understand what you were saying in letters and convert it?
Sorry for my previous post I was confused at your question. the computer can understand the "1" and "0" code and change it to letters and vice versa but if you write in numbers the code is different from the 1 and 0 on the keyboard so you can't.
