Performance
Under the hood, the AT&T Mustang is powered by a 416 MHz Marvell Bulverde CPU and runs on Windows Mobile 6 Standard. While this setup may seem modest today, it was competitive for its time, allowing users to run basic productivity applications smoothly. The device comes with 64MB of RAM and 128MB of internal storage, which was sufficient for handling the OS and a modest number of applications. Additionally, the phone features a microSD slot for expandable storage, allowing users to increase capacity as needed.
