Someone who updated successfully please share your customization code. Here are instructions how to do it:
1. Lock the screen of your phone. Press the menu button (left button) so that the screen is lit but still locked.
2. Press the home (central button) and back (right button) in following sequence:
Try several times if you can not do it the first time. when successful secret menu will appear. Go to Service info->Software info and find "customization version"
It should be something like 1241-3708_R3A (this is my code, your will be different but the same format).
Give us this code so we can update also.
