Hello guys! I was so headache about how to delete languages on my Iphone. I did delete languages pack a lot of times on many firmware below ios 4.0 using mobile terminal and all of these FW worked great without any problem. For the ios 4.0.1 or 4.0, when I press Y and return on mobile terminal, it said no such file on bin. I think 4.0.1 do not let anyone delete languages pack. Any ideals?
