[Android General] tweakradje:
I do have a character device (terminal?) /dev/ttyEFS0

Can one do anything with that?

With the adb logcat -b radio I got the log file for the ril/radio.

My attention was drawn to /system/etc/spn-conf.xml and after googling I found this file:

<?xml version="1.0" encoding="utf-8"?>
<spnOverrides>
<!-- @Author: HTC Shawn Ku @Date: 2010/02/23
This is a list for operator specific SPNs.
We will use below SPN for instead if numeric is matched.
Format is listed as below:
<spnOverrides
numeric="MCC+MNC"
spn="SPN Name"/>
-->
<spnOverride numeric="44020" spn="SoftBank"/>
</spnOverrides>

For my own sim that would be t-mobile NL: 20416 T-Mobile

Does that mean that I can override my locked provider?

I will try.

An interesting piece from the log radio file (also attached)

Anyone knows what "iccid: 893120630001779377" is. I tried it as unlock code but no avail.

Unlock codes ar always 8 numbers.

From the COM8 (in my system) I get the following info.

ATI

Model: GT-I5500
Revision: I5500XWJG3
IMEI: 359763034......
