34 Mar 14, 2006 DR: OMAPS00061468 - x0035544.
35 Description: SAT 27.22.4.22.2 SET UP IDLE MODE TEXT (Icon support) fails
36 Solution : In the function homezoneUpdateDisplay(), additional parameter has been added to the
37 function call addSatMessage() under the flag FF_MMI_SAT_ICON to support SAT Icon for IDLE TEXT display.
38
39 Dec 15, 2005 REF: MMI-FIX-OMAPS00058684 x0035544
40 Description: OMAPS00045726 / MMI-FIX-30439 Follow-Up : ifdef for FF Home Zone forgotten.
41 Solution: Added Feature flag FF_HOMEZONE for the function sms_homezoneCBToggle(U8 Activate_CB)
42 in this file as it has got the prototype for this function.
43
44 Jun 14, 2005 REF: MMI-FIX-30439 x0018858
45 Description: The homezone/cityzone tags were not being displayed properly.
46 Solution: Modified to save the tags properly in caches and also made the
47 appropriate modifications to update the same properly during mobility.
