Hi, In general boot loaders on mobile phones are a different area than for desktops. This is because mobile platforms are advanced system on chips containing multiple cores of different types sharing memory and peripherals in more or less complicated schemes. A mobile phone bootloader may be responsible for verifying and loading firmware for the radio part (baseband chip), applications processor and other subsystems.This means they are often purpose written for the specific chipset they are to run on and often they are proprietary to the platform or handset manufacturer.
That said there is nothing technical stopping a boot loader from being able to load different OS options. With the amount of flash memory rapidly growing I would guess that this is something we may see in the future since storing several OS options on the device is possible. I am not aware of any boot loaders that can do this today on a phone, but on dev boards using uBoot or a similar bootloader it is already possible to have this tyoe of setup.
