Since I have to fix some problems with addressbook sync for Blackberry my mind was circling around the possibility to generate log entries for some contacts that didn’t sync, while most do, and the possible cause, without reactivating the device.
Luckily i stumbeld upon a tweet from @bbgeek (via @filos) that might be of great help with this.
10 Hidden Features of Blackberry
Didn’t knew that it’s possible to reset addressbook with going into addressbook options typing RSET.
Addressbook is erased on the device and entries are synced again from BES. It works quite similar with calendar.
There are many other shortcuts I didn’t new before. Might not be interesting for casual users, but definitly opens many possibilities for troubleshooting.
