Upgrading MDA VARIO G4

[FabX]

Hi all,
I'm new in this thread so say me "welcome" :)
I bought an MDA Vario T-Mobile brand but SIM unlocked. I'm using it in Italy. All works good but language is english. I know english but I can't use T9 for italian SMS.
So... I'm trying to upgrade my phone.
Here are details:
IPL: 2.21.0001
SPL: 2.21.0001
OS: 2.21.2.6
GSM: 2.19.11

Is possible to change language or I need to do a ROM flash?
If so, how to find a tutorial?
Thank you!!!!!
