I've been searching and can't find a way to toggle 3G off on the Captivate.
Not only does 3G drain the battery where I am, I've found that the Edge network is more reliable for calls and text messages. I always kept 3G off on my iphone unless I needed to transfer some data where a wi-fi connection wasn't.

From the XDA forums:
Enter the Phone app.
Select  DEBUG SCREEN
Select  PHONE CONTROL
Select  UE STATE CONTROL
If you want 2G, select:
 CHANGE RAT TO GSM
If you want 3G, select:
 CHANGE RAT TO WCDMA
Hope this helps.
This is what I was looking for. Now since it is actually possible, there should be an app or a way to make a shortcut.

You can turn it off and leave it off if you choose to. The only time I go back to the setting is when I reboot the phone. The setting does not stay if you reboot or use flight mode.

Alternate method that's a little quicker to get to and survives flight mode. It does still reset when the phone restarts:
Dial *#*#2263#*#* (mnemonic: *#*#BAND#*#* for band selection)
Select  GSM BAND
Select  GSM ALL
Select "Select GSM All Bands"
Menu key > END

I am looking for a way to add a shortcut to *#*#2263#*#*
tried adding it to a contact but just dials it on sipdroid
tried LauncherPro activity shortcut, but I can not find it on the list.

There is an application in the marketplace called "SamServMode" that will bring up the service menu on Samsung handsets, which is more convient then having to type the access code into the dailer constantly.

You can save a contact, you just can't dial it directly from your contact list. If you save a contact, then start dialing, by the time you get to *#* the phone will display the contact and you can select it.
There's also an app called SGS Tools that has all the known codes and is updated whenever a new code is found.
