+ 	Mar 31, 2008 DR:OMAPS00164541 - x0082844
+ 	Description: OTA ATT - GSM-BTR-1-5618 - MS wrongly displays long number stored in ADN
+ 	Solution:No need to check for the current chararcter, if its a space.
+ 
+       Feb 02, 2006 DR: OMAPS00061468 - x0035544.
+       Description: SAT 27.22.4.22.2 SET UP IDLE MODE TEXT (Icon support) fails
