BlackBerry - Delete sensitive application data

As first what does exactly Memory Cleaning on your BlackBerry do? Well, Memory Cleaner clears various caches on the handheld including the temporary key store, content protection caches, address book caches, and the handheld clipboard. So it not only cleans sensitive application data from your device but it also speeds up your BlackBerry.
Your handheld's memory can contain sensitive information such as passwords, email message bodies, and private keys. To eliminate the risk of that information being compromised, BlackBerry supports a feature called Memory Cleaner.

All Java objects are stored on the handheld in RAM or flash memory. Normally, when a Java object is no longer needed, the memory assigned to that object is released to be overwritten by new data. When Memory Cleaner is enabled, the Java Virtual Machine (JVM) overwrites the memory using zeroes before it is released. As a result, there is no way to retrieve the data from the memory chips.

So how to use Memory Cleaning on your BlackBerry:
  1. From the home screen, press the Menu key.
  2. Select the Options folder.
  3. From the Options screen, select Security Options.
  4. Select Memory Cleaning.
  5. If Status is Disabled change it to Enabled.
  6. Press the Menu key.
  7. From the menu, select Clean Now.

This is glorious. I keep sanyig that the future is Android. And Google has proven me right. There is now a legitimate competitor to Nokia n Nigeria. The Apple of the world should beware and emulate good examples. Once again, thank you Google!!

Cafe World is a 100% online game on Facebook. You will need itrnneet access to play it as it can't be downloaded.The reason it's an online game is because it creates a community of worldwide fans who play and network through it. It also makes it easier for developers to release game updates more frequently.Cafe World is currently the #2 game on Facebook after Farmville.
