hi i am new in this forum and i badly need your help.

i have an 8gb iphone with 1.1.4 & 04.04.05

my first problem is abt 1cm of the lower screen was unresponsive

then i saw the touch setting & intalled it. it widened the area of sensitivity but unfortunately the lower 1/2cm still isn't responsive. its improved but not enough. pls help me

thanks in advance
