Is it possible to unlock USIM 3G (italy) to use like a GSM?

[maugiord]

Hi,
I have a QTEK2020 with SIM Vodafone.
Now the company where I work for, change the provider in "3".
They use USIM's that is not supported in my device.
Is there some way to unlock the Usim to work in the GSM way???
I want to save my money and contine to use my fantastic device (and all of the expensives accessories.....), nothing of illegal (like unlocking phones...).
Help please........
Thanks for everyone and beg your pardon for my terrible English.......

not that i know off ppl never unlock or change anything on sim cards
they unlock phones not sims
3 blocked their usims from being used in non umts devices
so ppl are more likely to use their services from where they make their money
