6630 Spanish Vodafon Blocked - How UnBlock?

Hi guys,
I worked in Barcelona and I bought a nokia 6630 from Vodafone, with a spanish sim.
:)
Now I'm back to my parents in Italy and inserting my italian sim (from telecom) the phone says: "SIM card not valid"
:???:
Someone told me that Spanish Vodafone block his phones...
How can I unblock this phone, I don't wanna buy another phone to use in my holidays... WtF!
:evil:
I tried to chnge the product code with a no-brand code using "NSS" but nothing happened...
I also tried other friends SIM and I got the same problem...
:???:
Can someone help me?
:cry:
THANKS in advance!

bro the unit you bought is not blocked. its just not open to all networks. you have to open the sp data. or unlock the phones network provider. use jaf box to unlock it or dejan's free unlocker using direct comport setting.

thx!
I'll look for and I'll try it for sure!
:D
