this post should actually solve the problem:

The poster offers the modems (partition 10 and 11) of the U8815-51 used in Latin America by some 850MHz 3G providers.
Sounds familiar?
from the source:
...
package_extract_file("modem_st1_LA.img", "/dev/block/mmcblk0p10");
package_extract_file("modem_st2_LA.img", "/dev/block/mmcblk0p11");
...
And that's exactly the reason why the ICS modems from B926 China Unicom from this post:
http://www.modaco.co...a11-in-any-rom/
do NOT work for 850MHz 3G.
Because the modems are different.
On a different note you could of course backup these two blocks to some safe place from your working GB ROM and start experimenting

Telstra 3G now works at 3G speed courtesy of this fix but my IMEI changed
Phone was about to be turfed after only seeing 2G speed, no backup ROM to restore to plus the OPs witty solution didn't work for me. The above fix did the trick. Now running Infusion (4.0.3) ROM with full 3G speed using a Telstra SIM. Only dilemma was my IMEI changed!!

CyanogenMod 9.1 ICS and 10.1 JB from Dazozo are now both multi-baseband.
No need to put any ICS UPDATE.APP on your Aussie GB and break 3G
Just put CWM 4 or 5 on, back up the system, and flash away :-)
Additionally you should backup your IMEI (5) and modems (10, 11) with :
ToolBox5iromV1.0.4.2.apk

Thankfully I had done this prior to doing any ROM changes and are contained in
G300_modems_Australia.zip if anybody else needs them. These files were saved when I originally had GB 2.3.6. Just use 5irom's backup function to create a 5irom folder, then drop the 10.img and 11.img in there and do a restore. This managed to get my IMEI back as well as my 3G link.
I needed to also re-install these modems after installing the official ICS 4.0.3 update. Else too I was once again in 2G mode only.
