Quick SMS Typing
When typing SMS messages, you have to wait some seconds before you can type the
next letter if it is in the same button than the previous one. For example try
to write the word "letter", you have to wait before you can enter the second
"t". A much faster solution is to press the # button twice and then the letter
"t".
