Is there any action that I can take for disciplinary action at work that onbly applies to me?

I recently got a new manager at the office where I have worked for three years. I have never been written up or had a bad review. A new cell phone policy was implemented and another employee told the manager that I was using my cell phone while at work. All other employees have done this as well. When I brought that to the mangers attention she said that she wasn't going to get into it. No one else was written up on cell phone usage as it seems my saying holds no weight. In the three years of employment and no write ups I have been written up twice since August. The first was for internet usage on a computer that the entire office uses during the day (especially when I am at lunch) For this I was told that because I did not log out that it was too bad for me. I was trying to get a job in a different area of the company which I was told I was hired. Once hr reviewed my file and saw the two write ups they said I can't transfer. Do I have ANY options here? I
