On a business iphone here
I'd been meaning to setup a home vpn for a while but never got around to it, so I configured my media center pc (it's left powered on) for a PPTP VPN last night.
If I was on O2 for my personal phone I would have switched immediately to another mobile provider, I guess I'll just have to change all our company phones from O2 when the business contract comes to an end. (around 20 iphones on O2)
We've been having occasional problems with O2 anyway, like getting them to get off their arses to fix the local cell which would send and receive calls but not data. (took them a couple of months to fix, lazy, lazy, lazy)
On the plus side, I've also configured a proxy that I'm going to get some adblock rules sorted out. So it'll mean speedier browsing. Oh, by the way.. plus side to a vpn is that the bbc iplayer works over it. I discovered this when I configured works vpn a while ago. The beeb does ip address checking and since it appears to them you're on a non-mobile IP address you must be viewing it over wifi.
