Due to limitations of the BlackBerry operating system, it may take a few moments to load your chat history database.
You may also try performing a full reboot on your BlackBerry if your initialization takes longer than 10 minutes. A full reboot solves various problems with your device. It also frees up application memory and shuts down applications running in the background.
You can perform a full reboot by removing the battery from the BlackBerry smartphone and waiting 30 seconds before reinserting it.
Unfortunately, due to the way the BlackBerry operating system is designed, there is a chance the application data is removed from your phone after a full reboot. If you do not have a memory card (SD card), your chat history will be erased after a reboot.
