Sony Ericsson :: W995 Assisted GPS No Longer Works?

i'm very familiar with the W715 and have been using one for the past 18 months and made good use of the AGPS feature - very fast fix times even indoors. Suddenly I now find that this phone is behaving as if AGPS is disabled in the menu. Master reset/Reflashing using SEUS and redownloaded my internet settings has not fixed the problem and even Vodafone UK have now provided me with a warranty replacement handset which performs exactly the same?! The world icon comes up for 5 seconds upon loading 'status info' just the satellites do not appear within the circles as they used to - instead they line up at the left/right of the screen until orbital data is downloaded via the strongest satellite instead of from the AGPS server. More worryingly my brand new W995 on O2 performs exactly the same which leads me to believe this is a SE problem and their rubbish about sending phone in for repair has really got me confused - how exactly will this help me? To clarify both handsets GPS chips work fine and will locate but the old slow way as if I don't have a data connection on the phone. But I do and can browse websites and check email so its not that. I've got Vodafone offering to send me yet another handset as their only solution, O2 I have a couple of days left to return under distance selling regulations but what I really want is AGPS working as it did before Called SE helpline today and they are the most unhelpful bunch i've ever dealt with. Telling me because the GPS works its not a problem, they totally ignore my comments that its not working WITH assistance. They also tell me they don't run any assistance server yet they must because you cannot change it in the settings anywhere and swapping network SIM cards used to be fine as long at there was a data profile setup.

Now two networks, two phones and no GPS assistance on either. Can anyone have a check on their handset and see if AGPS is working correctly or has a server gone down somewhere? Very lost and don't want to get blagged again when this technicial person rings me back to explain a bit better why my phone is OK and I just don't know what i'm talking about.
