OK, so I had my ipod touch for 3 months and the input jack went bad (no sound from left channel), so Apple replaced it (covered by man. warranty). So i bring home my "new" replacement and all seems fine at first, but I soon realize that something is just not right with the screen. The fonts in the menu screen don't look as sharp and when I watch video I get a headache. Its the same feeling you get when you look at a regular computer monitor and the refresh rate is set wrong. I'm going to back to the Apple store, but I fear that this problem is something not everyone would notice. I'm SURE something is not right - I had my first touch for 3 months and I just know something is off. Has anyone ever experienced this problem ? Also, I fear that this is going to be a hard sell to the Apple store since they just gave me a new one and its the type of problem that is not as apparent as the left audio channel going bad. What do I do if the "Genius" tells me there's nothing wrong with it ?? Thanks.
