my HTC S730 has no possibility to correct an enter by backspace. At HTC S710 the backspace works.
Do not understand why! What mobile phone works without problems?
There are two keyboard related settings, hardware keyboard, etc. There is another forum post that says to have both checked, well that fails miserably. I don't have it in front of me, but I checked the first setting and unchecked the second. This allowed me to enter letters using the number pad. Less than ideal, but at least it worked. I don't know why these guys don't use the standard in put method specified by the phone.
