It's an iPhone, get used to it. They are designer poser objects rather
than a practical, functional, communications tool.

Is that the model where the natural way to hold it covers up the ariel?

Auto/O2 shouldn't make any difference. It should (but remember this is an
iPhone) find it's "home" O2 network then roam to other networks when it
can't. AFAIK in this country there are no other networks that will allow
O2 phones to roam onto.
