I don´t have that problem. Using the latest firmware.

I am using the V3.2010.02-8 firmware. You can see your firmware version by calling *#0000#.

I am using the V3.2010.02-8 firmware too, i even reflashed my phone today with both images: fiasco/rootfs and eMMC, but that didn't solve the problem as well as for you too.

So, i'm really getting mad about that

A helping hand from experienced users is needed. Please

I noticed that in Phone settings, i can save the following changes:
1. call waiting checkbox
2. Network selection (manual or automatic)

I cannot change:
1. network mode (3G, Dual, GSM) it is always 3G no matter what i try to change and save
2. call forwarding - i can't turn it off, it has same preset phone number to forward the calls, which can be changed with one from selected contact, but can't be changed if i just manually edit the number (to change the last number, let's say) it says "wrong number"

The thing is that with 3G/GSM/Dual network selection applet i cannot change network modes (as with phone settings too) and earlier, i used to use 2G/GSM mode, as the battery lasts longer with it, rather than with 3G.

This is really strange... Now I tried v2 and v3 and none of them let me choose 2G. I'll try V1 and see if that helps. I'll report back!

V1 won't let you use your sim
been there, tried that already

Hmm... v1 cant find my sim card. I know that v1 had problem with some sim-cards, but I did have v1 on my old n900 without any problems...

it's not because of that, it's the other reason.

As I said in my last post it was working with v1 as v2 was not even out when I got my phone and I could make calls...

I have not tried to change network mode but I can confirm that call forwarding cannot be changed. I tried many times to disable it and each time when I return to phone settings it is turned on with the same network-default phone number.

I am not mad but it is irritating that phone does not listen to me but to SIM card.

Firmware 3.2010-02-8 flashed by me (not OTA-upgraded).
I have rebooted, turned phone off, removed battery - situation stays the same.

This bug is incredibly annoying.

I need to stay on one specific network while roaming, otherwise my data charges go through the roof.

So, the natural way is to go to Settings -> Phone and set "Network selection" to Manual, and then select the appropriate network. all good. but once I hit save and exit the setting application, and then relaunch it - Network selection is back to 'automatic'.

this is incredibly frustrating and has cost me a lot of money already. Where are the settings stored? I'd like to manually alter them to make sure the phone sits on a specific network, and if there's no signal, it should just go offline, not switch to another network.

Edit: I'm using PR1.2. tried everything, rebooting, zapping the settings - you name it.
Edit 2: I'm on the operator 3.
