I get my yahoo and gmail on my PPC and my PPC connects to the 3G network every 2 hours to download the mail. Once my PocketPc establishes a 3G connection it will not terminate it automatically and will stay connected to 3G, which in turn drains the PPC battery rather quickly. I found out 3 ways to get the 3G connection terminated, 2 manual and 1 automatic ( 2 of these involves Registry Editing ).

Manual Disconnection

1> When you are done with the 3G connection , just keep the call Disconnect button ( the red phone button ) pressed for a few seconds and the connection is terminated.

2> Get a disconnect button & time of connection in bubble when you click on the connectivity icon ( usually the 3G/E/H icon on top)

For this hack you will need to edit the following Key in the Registry

HKEY_LOCAL_MACHINE\ControlPanel\Phone\Flags2

you can have 3 options

0 – No disconnect button & time of connection in bubble
8 – Show disconnect button in bubble
16 – Show disconnect button & time of connection in bubble

Automatic Disconnection

3> With this Hack we can set a predefined number of Seconds , and if the 3G connection is idle for this amount of time the connection gets disconnected.

For this hack you will need to edit the following 2 Key in the Registry

HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\

the 1st key is DWORD CacheTime the number denotes the number of seconds to wait before the auto disconnect, I have mine @ 60 seconds

the 2nd key is Multiline value / String SuspendResume which can have 2 values

~GPRS! :- 3G always On
GPRS_bye_if_device_off :- timeout after CacheTime

and you will need to set it to GPRS_bye_if_device_off

Hope this helps you all.
