Graphical lock and rotery

Is there a way to use both a graphical/pin lock, as well as the rotery? I hate leaving my phone unlocked?

Unlock pin

Can someone please provide me with the code you enter in the dialer to bring up the network unlock screen? I don't have another sim. Thank you

Connection band info

Hi, does anyone know a way to determine what hspa/gsm band your phone is connected to the mobile network on in cyanogenmod 7?
Thanks

The CM wiki will list available service codes to type into your dialer. I believe there is one that will do what you are asking.

Network Lock

Hey there
I recently scoured the xda site for instructions on how to remove the network lock (Currently Three,UK) from my SGS4 GT-i9505.
I came accross the *#0011# method posted here
http://forum.xda-developers.com/showthread.php?t=2282683
I have followed the instructions to the letter but cannot get past stage 4 (press menu, press back and your at the main menu of service mode) well the screen doesn't change and there are no menu items i can select i.e. the UTMS section i need
If any one has had similar problems or knows of a solution it would be greatly appreciated.
Thanks
Confused n00b :banghead:

Just found our answer...see las post by me...
Second option is to phone network (in my case Three), they told me i have to have the contract at least 1month then i can pay £16 for the code to unlock the device

The search function here on XDA or Google. Both will bring you to the answers you need.

I would try fasgsm.com or call your service provider for the unlock code cause the free hidden menu unlock method don't work for everyone. However the free method did work for me
