Patch has been applied.  Note that GET RESPONSE or the CSIM equivalent is the 
only sane way to do this as we also need to support cyclical and record based 
files.  Is there any other way to find out the total file size and the record 
size on the Neo besides GET RESPONSE?

For Record-Based files you can use CRSM=178,<file>,0,0,0 to find the record size, 
but not the total length of the file (e.g. how many records there are)

If we can obtain this information, then we simply have to maintain a different 
implementation when ti_calypso is used.

And I can confirm that GET RESPONSE simply doesn't work on the Freerunner:

AT+CRSM=176,28423,0,0,0
STR=`AT+CRSM=176,28423,0,0,0'
RSTR=`+CRSM: 103,9'

Ok, EFimsi exists with length 9

AT+CRSM=192,28423
STR=`AT+CRSM=192,28423'
RSTR=`+CRSM: 111,0'

Unknown technical problem.
