It’s great if your phone comes with pre-installed applications that you actually use, however most phones such as the Samsung Galaxy S2 Epic 4G Touch come with bloatware. These are applications pre-installed on your device but which you don’t actually (or frequently) use and which you cannot uninstall. The only way around it is through root access.

You can opt not to remove such unnecessary applications, however they tend to slow down the performance of your device and consume significant storage and RAM. There is now a way to get rid of them–Calkulin’s Bare ROM Converter, an application developed by XDA Developers member Calkulin.

The Bare ROM Converter is meant to bust most of the bloatware on your phone. Removing such pesky apps can help you save some precious memory and your phone’s performance will most likely improve.

According to the developer, the Bare ROM Converter moves apps into a folder on the phone’s SD card, where they will stay unable to bog down your system any longer.  The following apps are moved to /sdcard/Removed_Apps as of version 2.0 of the Bare ROM Converter:
