Yes, ACWP uses the supl server or it should. Yours is an interesting and surprising result provided that it followed a reboot. I get nothing usable (no reset just following a reboot) - generic country or nothing at all - and that is why I suggested ACWP over AGNSS as a test as it relies on a position server alone. Any obvious reason re ISP (wifi/gprs?) as to why Vodafone might allow you to use the service?
