Height maps and mobile gaming

Hey Guys im just checking in with you all,

From my knowledge of using height maps in UDK for the past few months the ups and the downs and the long hours it has come to my realisation that the landscape editor and terrain editor at this point will not work for mobile gaming etc platforms such as android and iPhone  im not 100% sure if PS vita or PSP can take height maps or that any other engines such as cry engine support use of height maps in mobile gaming but at this point UDK does not support it, if anyone knows an engine that can use height maps on mobile platforms please email me and let me know.
