So I did something very stupid with my new Sony Xperia Z1 phone and I have an equally dumb question. I went to put the micro SIM in my phone and noticed there was a white piece of plastic sticking out. I thought this was to protect the slot and so I pulled it out. Only when had I removed it did I realise this label contains the phone's IMEI number and was not supposed to be removed. I only found this out when I contacted Sony Customer Support. As I said this is a stupid question, but have I invalidated the warranty by doing this? Also, I assume I haven't damaged the phone. It seems to be working fine... Thanks
