yeah I was happy enough with my 5s. However a week ago it refused to charge. As its insured and I was only a year into my 2 year contract I thought I could just take it to the o2 shop and they would sort the problem out for me. However after testing it on one of their chargers they sent me up the Apple store in Stratford where after waiting ages to be seen by someone I was told it was either a software fault or the charging port needed replacing, they also informed me they couldn't fix/replace it for free as I was a week outside of the phones one year warranty. They told me to go back to the o2 shop and try to claim on the insurance, however when I did that they said I was not covered as the insurance only covers accidental damage such as dropping it or getting water in it. They said my only option was to buy out of contract and upgrade to the iphone 6. So I paid £240 to do that and now have just began another 2 year contract.
The next day my mate came round, blew into the charging port, plugged it into the charger and it came back to life! I managed to sell it back to o2 for £187 so recovered some of the money spend on buying out of the contract. Getting used to the larger screen now and I suppose the extra battery life and improved camera quality is a bonus..
