Wow, kinda crazy. And I guess I should have searched better first... sorry. It wouldn't be such a big deal, except that at night I have it charging and I like to use it to browse and check mail and such in bed, and the cord is sort of short and I'm on the left side of the bed.... So I have to rotate the phone with the cord sticking out the right, and then making a sharp turn back across itself to the left. It's tight and makes me have to hold the phone over to the side just a bit; a little uncomfortable. Probably not the best thing for cord life either.
Hopefully this is something that will be changed in a latter OS update - no good reason I can think of why it only goes one way. I actually like using the phone the way it rotates now with the hard buttons on the right, it's just the charging in bed thing that is annoying.
