My iPhone was stolen, can I still get an upgrade? (O2)?

Hi, I recently had my iPhone stolen in Paris and I have insurance but it won't cover it because the iPhone I have, (the 4S) has gone up in price:/ I then found out that I'm due to get an early upgrade from O2, on the 20th April to be exact. But I looked and it seemed to be suggesting that I would need to hand the old phone in… Which I obviously can't do as it is somewhere in Paris. Is it still possible to upgrade?

Also… What actually happens when you upgrade? Do you get the newest iPhone? I'm not too keen on the 5 and would prefer to have the 4S again but I don't know if that's even possible:/

Any help would be much appreciated!

Can I buy an iPhone and switch it to a different carrier?

I'm with Verizon right now but I'm planning to switch to cricket soon. I don't want to buy an unlocked iPhone, so I was wondering if I could buy a phone from Sprint or AT&T and switch it to cricket?

I dried it off and it was fine, the sound was working and everything. 2 hours later I was putting the ringer on and it said headphones which I didn't have any in for the past 3
Days. I turned it off and back on and now where you see how loud the ringer is (the squares) its not there. It says ringer and everything. I have no sound at all.
