So I've gone (back) to CM10 (CM10.1 is way crashy on these it seems, always running out of RAM) 4.1.2 again. Since its like a new device compared to GB 2.3.6
Seems to be sweet as.
I notice the default CM10 modem is JVT. Now, last time I went to JB 4.2 CM10.1, I don't recal the included modem but the coverage out in the wops (Kaiapoi) seemed to be a hell of a lot better than the GB XWJW4, and beat JVT also it seems.
The stock CSC is XSA (unbranded Virgin australia release) and latest official ROM included XWJW1 modem.
Now, on the off chance the network out there has not changed, and the modem is at fault. What version ICS/JB modem has everyone else found works all kinds of aweome on VFNZ
As I understand it, XW is the wide european use modem, also used in NZ/AU. But can't seem to find similar region coding with the ICS/JB modem versions on XDA
I'm open to suggestions to try different ones if the JVT has been found by you guys as pretty bad in NZ, and I need to put on XXJW4/6 or similar.
Perhaps someone with an official NZ JB unit can shed light, or are the modems also locked to type of device also.
