Hi,

I have read the Patch A2 platform CID53 RED tutorial and SE-Sense forum.I'm a bit confused.Some said it's not possible to unlock a Red CID53 and need to convert to Brown and other said the opposite.And some said no more free method to convert it to Brown

I actually need to just Unlock the SIM lock of a CID53 Red C510 .I don't want to add or change any features or skin of the phone but just let me use other phone network.Can anyone help?
Thanks in advance
