If it is any help (and it probably isn't, actually) I found my Galaxy S slipped very neatly into a marsupio I already had. Marsupio = front pouch, think Kangaroo, you may have a different word for it. Anyway, there's a fat pocket in front and a narrow one behind and the phone is slim enough to slide into that very comfortably. This would be true of most slim phones, I think. I'd be happy working out with that, I'm certainly happy carrying it all day.
