many of the recent windows mobile devices support the network feature "Alternate Line Service" ("ALS") (http://en.wikipedia.org/wiki/Alternate_line_service) which allows to have two phonelines on one simcard.
One can easily switch between the lines with a dedicated menu, as seen here:

(on a Xperia device).
The appearance of the second-line menus relies on an entry in the Customer Service Profile (CSP) of the subscriber simcard.
For instance, the menus appear when using simcards of Orange(UK) or One(AT), but not with T-Mobile or Vodafone simcards.
As some people find these menus annoying, especially when they are not subscribed to the ALS-service, they can easily remove them by setting the registry key "ShowALSPage" in HKLM/Software/OEM/PhoneSetting to "0".
Now, I have a particular problem:
I want the menus to appear even though my simcard does not have the necessary entry in the CSP. I am subscribed to the service with eplus(DE). However, this operators simcards only support a preliminary ALS-standard which was introduced in collaboration with Siemens almost ten years ago. Since Siemens mobilephones have vanished from the market, it would be nice of eplus if they would eventually update their simcards - what they still reject, unfortunately.
The eplus simcards hold the value 0x55 in the CSP, while, according to the final standard, 0x80 is expected for ALS capable sims. Till now, the only mobile phones interpreting eplus(DE) sims correctly are Siemens and the most recent Sonyericsson UIQ phones.
Other mobilephones would still work with eplus(DE)-ALS service. For instance, on Nokia phones one can easily unlock the menus using CSP-override. Some Motorola phones simply always display the menus.
Is there any way to make the ALS-menus appear on Windows Mobile 6.0 devices, like the Xperia X1?
