I think by "backwards" they mean it has the wrong part in front of the star/roundel and the wrong part behind the star/roundel. These are technical details, which perhaps the skinner did not understand or know when the skin was made. Please take said issues up with the skinner himself/herself, and don't blame HTC for that. If you know (for a fact) that there is some inaccuracy with a skin please contact the skinner and ask politely if they were aware of this. Some people have to jump through hoops just to get their skin to display properly (I know I had to with an old 109E I did before 2.06). They may know something you don't or they may have had to make a choice and did so.
Keep that in mind.
