If you could, upload the Turkcell rom to a third party site and link it here. I will download it and see what I can figure out. Huawei has the U.S. blocked from downloading roms from their site.
Alternatively you could download and use one of the many CM7 roms available for the U8650 as they will have the notification widget by default. I am curious what you find best in the taiwan version or if it is simply a language thing.
