Hi Guylhem, hope you're covered from your terrible accidant! Congratulations on your Ph.D, Doc :-)
Yeah, it's fun with the SIMpad. Almost a year after I resigned from OpenSIMpad.org, some folks relaunched the site and joined OE to work on that. I'm glad to see that happening although I no longer have such a device.
The SIMpad was groundbreaking, ahead of its time. Alas, SIEMENS really screwed up marketing that.
All the best.
