Oh damn!
I just stumbled in the kitchen and banged my hip against the door knob. Fortunately my hip is fine as my phone took the brunt of the impact! The screen is smashed, though it still works.
I figured I might as well put in an insurance claim, given I have been paying the premiums, and get it replaced. Should be arriving this evening.
This should be just in time to cancel my insurance payments as it is going up from £6 to £7.99 in April, and I am changing my phone service from EE to something else in August.
Just need to download and clear all my data now, and then reset the phone to factory settings, hopefully without erasing my sim card.
Just need to figure out saving my calendar...
