I'm going to buy a O2 GmbH himalaya will it be unlockable?

[LMP]

What is the latest radio version?

Can it be downgraded in case it's not unlockable.

Please let me to know because I'm going to buy it this week

Thank You

Ps

By example 1.14 radio stack is unlockable?

see the unlock section on this site.
AFAIK all sim-locks can be removed. BTW Your O2 device will come with a 1.60 or 1.66 rom most likely.
