i have no idea why but my 1.1.3 jailbroken ipod touch suddenly lost the ability to touch. this affects only a small centre portion of the screen now it is not touch responsive and it may work if i just keep on tapping on the same area with different angles. but i am sure that there is something wrong. this is the first time this has happened and i find it quite weird as i had my ipod since last christmas and i never heard of such things. people help me the centre portion is quite important.
