&gt; I think we can start by moving the stuff step by step into the phone,<br />&gt; if anyone wants to work on this, it would be much appreciated.<br />&gt; <br />&gt; <br />&gt; Layer2 (LAPDm) should be relatively simple, but starting from RR/MM/CC<br />&gt; and the cell reselection I expect some more difficulties...<br /><br /><br />One thing to keep in mind for anyone trying that is that you can&#39;t do unaligned access ...<br />and we do plenty of them ...<br /><br />So either you need to fix that in the code, or catch the exception, and emulate the access ...<br /><br />Cheers,<br /><br />     Sylvain
