I have a two year old i9000 which does not wake up on pressing the home button. This device is pre Gingerbread.
I have a similar device which I have had for the same time and at some point I updated to Gingerbread. This device wakes on home button OK.
I don't think this function came with Gingerbread but I cannot remember what tweek I applied, and cannot find any tweek on Web.
Can anyone help?
