To build applications for the phone requires the ARM Developer Suite of tools, which are used to compile and link a project that has been developed using the PC-based BREW SDK, and related tools. Running an application built using the ARM tools requires a BREW-enabled phone, a data cable for establishing a serial connection to the phone, and file copying software such as QUALCOMM's BREW AppLoader application. See How to Build a Downloadable BREW Application for more details.
