Re: [PATCH] Sending catenated messages in incorrect order

I'm -1 for this patch and -100 for that SMSC.

There's no reason for an SMSC even to look at those informations. The  
SMSC does have no need to reassemble the parts of that SMS so it  
should just blindly transport every individual part. You should shout  
at the guy running this braindamaged SMSC (is it maybe from comverse?)
