This appears to be Sprint's policy. It happened to us when we left INSINC 
(Sprint Canada) for another provider and they refused to let us take a 
CIDR block with us. Fortunately, we had not yet allocated any of those 
addresses to customers.

My recommendation: If your addresses do not come directly from a NIC, then
get the allocation IN WRITING and SIGNED! If your provider will not sign 
for it, then apply directly to the NIC.
