I have a Telus LG P500, that i unlocked today it is quad band 2100 / 1900 / 1800 / 900 / 850 MHz, EDGE and HSPA, but i didn't do my research... so it doesn't work on wind mobile network which requires 1700/2100 MHz to work on their AWS network. is there a mod, flash, or app that can change this frequency?
