Systems and methods for dynamic installation of modular software applications and operating system components are provided. A wireless communication device sends a request to a software module server identifying a requested software module. The software module server responds with an instruction set for installing the software module and the software module itself. Upon receipt, the handset executes the instruction set to install the software module, making any necessary adjustments or deletions to data in persistent storage in order to accommodate the new software module. Subsequently, the wireless communication device is reconfigured or rebooted to complete the installation and configuration.
