 $History: MmiHomezone.h

	15/02/02			Original Condat(UK) BMI version.	

	Jun 14, 2005 REF: MMI-FIX-30439 x0018858
   	Description: The homezone/cityzone tags were not being displayed properly.
   	Solution: Modified to save the tags properly in caches and also made the 
	appropriate modifications to update the same properly during mobility.
