I stumbled on some new info on this in another forum. New to me anyway. Luckily I haven't had to try it... yet, but I read that turning mobile network off then back on again may fix the mms "msg download unsuccessful" error. Still sucks to have the problem at all, but this would be an easier fix than having to hard reset all the time if it works! If anyone has to try it before I do, let us know the result!
