E-junkie Admin has never worked on the iPhone or other devices that don't support Flash, so it's not something broken that needs to be fixed; it's entirely new functionality that needs to be built up from scratch, since nothing of the current Flash/ActionScript-based Admin can be carried over as-is to the new DHTML-based Admin. Quite a lot of the configuration logic is managed in the ActionScript layer of things, so it's been really tedious, thorny work replicating that from the ground up in an entirely different scripting language.
Development keeps their cards pretty close to the vest, so we in Support cannot report on their progress nor make any promises as to when they will be done with any given project. I can only say the new Admin being completed is definitely a matter of "when", not "if". I really wish I could say more, but I just don't have any more to say; we in Support just aren't privy to that information.
