i-phone buttons not working in some applications
hi folks, come across a problem and any help would be much appreciated. Imported a new 8 Gb i-phone from America a while back. Seemed to be working fine but now all of a sudden, the bottom row of buttons do not work in text, e-mail, youtube and safari. (in text for example it is the exclamations button, space bar and return which do not function). If safari is turned to landscape all of the buttons work fine. I have restored and went through the jail-break routine a few times since but the problem persists. As it has been brought from America i have no warranty here.
Thanks in advance.
