No matter what you choose, the keyboard SIP is always selected after a soft reset. Dosent this get to you after a while. Enter SIPChange , now you don’t have to select your favorite SIP each time you reboot.

SIPChange has two execution modes. If executed with no parameter, it
presents the list of SIPs available on your device and allows you to
select a default. Once set, this information is stored in the registry.
If executed with “SET” as the parameter it minimizes itself, reads the
default from the registry and waits 10 seconds. When the timeout
expires, it sets the Current SIP to your selected default and closes.

How to use:

1. Copy the attached CAB to your device

2. Tap on the cab using file manager to install.

Now open SIPChange by tapping Start->Programs->SIPChange. You
will be presented with a list of your available SIP. Highlight the one
you want to become the default SIP. If you wish, you can change the
default delay as well. Now tap the “Select” button. The SIP will be
changed to your selection and SIPChange will close.

That’s it! The next time you (or your automatic nightly backup) resets
your device, the default SIP will be reset to your choice (best of all no need to tinker with the Registry).
