I think some phones just have swapped IQ lines for easier routing ....
This wouldn't explain why the C122 GSM-850/1900 needs the "I/Q-swap" for GSM-850 TX only. And if I remember, Harald tried it with a GSM-900/1800 phone on GSM-850 (of course there are filter issues in this case) and it required the "I/Q-swap" again for GSM-850 only.
Best regards, Dieter
