Thank you for responding - i appreciate your input
The CenRep mods that effect system caching i have made are in 10283344 (where i set system cache to unlimited), 101f8557 (Web cache increased from 1MB to 10MB) and 102072c6 (FOTA cache set to 1kB). i made the same mods to the E72 and N8's CenRep as i have to the E6 and have had absolutely no issues with either one.
This problem i am having with the phonebook is the only bug i have experienced yet, and it is only present with the E6. i modified the CenRep in all three sets of firmware for the three devices i have almost identically (obviously kinetic scrolling does not exist on the E72).
i flashed the OFW as a test and the problem is non-existent, so i know the firmware files are ok, but i went ahead and deleted my edited batch and going to start over as perhaps i accidentally deleted a file of which i am unaware.
