Hi there.
I have my CDMA Sprint Touch Pro device and want to use it in another country with another provider.
How can I unlock it?
Or I just need to change something inside ##778# (I know the pass)?
Found some ways to unlock for custom firmwares but not from provider...

And is there a spanish firmware for it? Or MUI?

P.S. I'm newbie in CDMA.
