Broken Ericsson T68

I've discovered that Ericsson T68 is REALLY broken!

When receiving SMS's, there's at least two bugs.

First non-bug is that the init string have to be
AT+CNMI=3,3

Because that's almost the only parameteres accepted:
AT+CNMI=?
+CNMI: (3),(0,1,3),(0,2),(0),(0)

but that's ok, because it delivers the message to kannel anyway.

But then when I receive a message:

+CMT: 31

Without the colon!!! Broken.

But it gets worst:

Ericsson counts the wole string, with SMSC included!

079153911116161604098519494002F739002030515191730005F4F29C5E06

I have 07 bytes for SMSC and 23 bytes for PDU, I should receive 

+CMT: ,23


Bad broken Ericsson...
