Someone else would probably have this down better than me, but since nobody else is answering, I'll offer my vague (and possibly incorrect) recollections.
Ericsson had a big fight with Qualcomm a while back.
There is also a big long story about Qualcomm and CDMA patents. I think the GSM version of CDMA is somehow different enough to get away from Qualcomm's royalties, or somehow pay them less.
It may also be less trouble to re-design a phone to use different frequency bands than to design it to use a completely different chips.
