yup i hv installed itzz fast than .54 
I have rooted my phone and flashed the B.89 firmware from the link you have posted. However now, I am not able to root my phone again(as a result my Titanium backup I did before flashing is useless.
Any pointers?
Seems faster 
I have a problem with gps.(B.1.89)
Can someone upload: / system / etc / gps.conf (from C.1.0).
Thanks
Will all stock users get a notification in PCC or do they need to flash?
If so:
Do you assume this because there is an italian firmware or do you have a source that confirms this?
You need to flash .89 firmware, than flash b.1.10 kernel only! After this step you proceed rooting. When you're done rooting the phone, you flash back b.89 kerlnel only. You're not flashing whole .89 firmware again, just the kernel.
That's how you root 
And yes, there is a lot of bloatware, and I've deleted all of it after rooting the phone :smileygrin:
It seems faster and smoother, there is no lag any more in call history as I use to have and surprising there is more free ram than usual (from b.10, c.10 and b.54).
Please release a version for United States. Can't believe I'm still using B.1.10
I have a problem with (a)gps. In this version of software (B.1.89) SYSTEM/ETC/GPS.CONF file has the following:
SUPL_HOST=supl.posta.tim.it
SUPL_PORT=7275
SUPL_VER=
Can someone write exactly what is in this file in version C.1.0.
Thanks in advance.
