The Samsung SPH-A900 (also MM-A900, A900, or "Blae") is a CDMA cellular telephone . In the US it is currently carried by Sprint-Nextel, and by Bell Mobility in Canada. Its design is considered to be largely similar to the Motorola RAZR V3 by some, a popular model of thin clamshell-style cellular phones. However, there are still major differences between the two models. A revision to the A900, referred to by Samsung as the A900 Plus and marketed by Sprint as the A900m, features different materials on the casing (plastic casing replaced the previous aluminum case, allowing for better signal range, especially for Bluetooth), improved GPS functionality, and improved T9 word prediction software. Additionally, support was added for Sprint's standardized MIUI user interface, which is closely based on Qualcomm's uiOne.
