Not entirely sure what happened, though any duplicate posts should be merged automatically.
The site may behave differently on phones/iPods but it should still be functional. Things opening in new screens is likely because it doesn't support our way of handling it being done on the same screen. White screens can happen sometimes when I'm updating something but they should go away if you refresh. Otherwise that would be another issue with the phone.
You can't see any smilies? Or the button to use a smilie? Our advanced editor is disabled on mobile devices because they don't handle it well, so that would be intentional.
As for the salmon borders or blue text, that shouldn't be happening. The way our style is loaded, it may be possible for some things to appear in unusual colors until the page is fully loaded.
A mobile style is coming "eventually" anyways, which would provide a better experience in situations like this.
