ios isnt going anywhere. It will be around for a long time. However it will need to adapt and be open to more cross platform abilities. What android does have is the ability to allow users to go from one android phone brand to another android phone vendor without skipping a beat. With apple, you have to stay with apple. Nokia is adapting and so will Apple. How Apple responds to 4G capabilities will be critical. Battery life will be critical. Perhaps they will need to allow for eaily removabe batteries. Never underestimate Apple as they will adapt and change quicker than others.
