There was a discussion about Bost on the oesf.org forums and possible ways to get Bost support where discussed. There was a description how to patch the Siemens loader. Some time later smutny told me on the IRC that he was able to get into Bost with using the testgrid - many thanks to him! I now was able to test his way and was quite impressed. If you like history stuff you can browse the history of this page to see how to patch the loader etc. I removed that because of the much better usage of the tesgrid.
It is simple. Connect to your SIMpad as you do for Siemens loader. Start your device while you shortcut pin one and four on the top left of the testgrid - thats it!
Here is the output of the Bost help. The possibilities are awesome!
