I have the Samsung S2 T989D. I am running ICS verson 4.0.4 and am trying to update my OS by connecting my phone to my computer with Kies air. My computer recognizes my phone and it shows all my stuff on my phone but it doesn't give me any options for updating. There are no prompts or tabs that I can click to update. Am I doing something wrong or am I not able to update this phone.
