So I switched to my iPhone 5 (Nano SIM) today, after mainly using the Xperia Z (Micro SIM) with a small adaptor thing. 

I didnt notice at the time but it appears that one of the pins inside has become bent, and I think it might relate to that little plastic adapter. I didnt tug or anything, I would have stopped otherwise.
But anyway, when I tried to put it in about half an hour ago, it wouldn't work. SIM wasn't recognised. The phone saw something go in, and rebooted, but still said no SIM when it loaded. 

I tried to take it out, but the thing is stuck and won't move unless I force it which I'm terrified to do.

I feel horrible, because it was a gift and I hate knowing I broke someones gift to me. But, I need to know how/where I can get this fixed so I can use it again as intended. This time with a proper sized SIM. 

The phone is imported, from Hong Kong I believe. Its the C6603 LTE model, and was originally purchased from E-Info (AKA Expert Infotech) on the north shore of Auckland.

I dont know whether to take it to them or deal with sony directly, as when I've had iPhone problems I've gone right to Apple as they're generally faster. 

Thanks, 
Sam.
