Oded's AT2 patch

Here are my thoughts ....

This patch uses similar workings to my original work. The better thing 
about AT2 vs. AT is that it has private memory which allows no 
modifications outside this file, as well as the other advanages of this 
phase2 thing !

Before the patch is applied, we need a clean patch. The one submitted 
fails to patch .... after doing it by hand .... I have found the following 
:

Currently this works quite well. I have only been able to replicate tests 
for SMSs which already reside in SIM memory b4 bearerbox startup. It 
manages to read and delete from memory A OK.
From its operation I can see that it would work for SMSs which land in 
memory during operation. I am quite confident that this patch will improve 
AT2. I can also suggest leaving AT2 intact and creating AT3. I just wonder 
wether people would patch AT3 with the same changes they make to AT2 ?
If we do choose to create AT3, then I must encourage maintainers of the 
AT* modules to port patches to AT3 as well as AT2 and vice versa.
