Engadget reports that O2 has posted a notice on their website
that both the 8GB and 16GB iPhones are no longer available in
the UK. This confirms earlier reports that O2 had end-of-life’d
the 8GB iPhone, though it appears even the 16GB iPhone has also
run its course.

While the next generation iPhone has been long rumored, most
expectations have pointed to an announcement at Apple’s
Worldwide Developer’s Conference which is not scheduled for
more than a month from now.
