the main difference besides the name is the 3G frequencies on which they work

MT15i	900 / 2100
MT15a	850 / 1900 / 2100 / 800

flashing other firmware (flashtool) does void your warranty, you might be able to reflash to it's original firmware

even if you use the MT15i firmware on your MT15a phone, the name will change BUT your phone will work as a MT15a
