I just got back an answer from them.  The reason of the patch was 
because when the supplicant was doing EAP negotiation between AKA-PRIME, 
AKA, and SIM, for some reason the server was using the wrong Identity. 
I asked them if they tested a "forced EAP-SIM" situation with their 
supplicant.  We'll see I guess :P

Well you are probably right, but when providers will start pushing 3G/4G 
offload for real (if they ever do), there are not many ways of doing 
it... I think :P  The reason of those tests on our side is to support 
WISPr and/or NewGen hotspots with our product.
