The official instruction from BlackBerry
On the BlackBerry device, the following error message appears after pressing the Mute button, accessing an application, or performing a hard reset:
523 app. error. Reset.


Resolution

To resolve this issue, complete the following steps:

1. Upgrade to the latest version of BlackBerry Desktop Software.
2. Remove any recently installed applications on the BlackBerry device, then install the latest version of BlackBerry Device Software on the BlackBerry device. For more information about how to upgrade BlackBerry Device Software, see KB03901.

It's recommended to buy a microSD card to store your media files on, so you don't run out of memory on your device.

Depending on what OS your BlackBerry is tells you what size microSD card you can buy. You can check under Options ' About (will be listed as v4.xx.xxx). Look at the chart at the following link to see what size you can obtain -http://www.blackberry.com/btsc/KB05461

On the BlackBerry go into Options ' Media Card. Recommended media settings are as follows:

Media Card support : ON
Encryption Mode : NONE
Mass Storage Support : ON
Auto Enable Mass Storage Mode When Connected : YES

Mass Storage mode allows your BlackBerry to act as an extra drive when connected to your PC. So it will show up as an extra drive letter in Windows Explorer. So you can just drag/drop media files onto your media card and vice versa.

Or if you use ITunes, you can you the Media Sync to synchronize with the device. Read up about that here:http://na.blackberry.com/eng/devices/features/media/mediasync.jsp#tab_tab_overview
