I have my unit rooted, thanks to Z4root. Dynavin is unable to make the 3G modem work. They test it in China and they say it's working well. The unit comes with a chinese APN set up, and even if I change them to my spanish data provider, it still fails (shows a very annoying T-mobile all the time).
Which file should I edit to change the default values to mines? Is there a file in which I can dig to see something strange related to the Mobile Networks setting?
