Dreams definately having meanings...and varied at that. Sometimes dreams are a reflection of things we are struggling with and sometimes they are warnings....etc... In this case I think maybe this is a precusor of things to come... The world we are living in today is not the same as even 10 years ago...before 9/11. After 9/11 we went into a fast track of change...most not good. In your first dream nothing was as it was supposed to be...everything was jumbled and fell apart...this sounds like deception to me in that you think you are getting one thing and find out it's something else...the model of the phone outdated by many years...seems to represent things going back to how they were many years ago...only in this case even trying to go back doesn't work, as the phone falls apart.
The second dream takes place in a mall...and you say that you normally would not go to a mall...makes me think that you may have many changes coming into your life that will be uncomfortable...pushing you outside of your comfort zone...
