first of all it would be of interest to find out about exact serial# and 
GSM-FW revision of (your current and) former device, so we could possibly 
trace back the manufacturing process and scrutinize the logs, as well as 
FW-version etc.
Can you give any more details (pointer to ticket, reseller, dunno what) 
please.

Did you run the tests with same kernel and rootfs on both devices, and still 
different results for GSM?

Which SIM/provider are you using?
