That just might
blinkin' well explain why I've spent all afternoon playing with every setting under the sun to get my phone working! I thought it was an issue caused by O2 forcing a "connectivity update message" on me last night! Internet and MMS that had been working for years (literally) suddenly stopped working today (well, MMS is still fubar, but I can live with that).
However, I'm online again and I've been connected for the last few hours with no problem, streaming music (so I'd notice an interruption in service). That's in Folkestone, for what it's worth...
