The thing I find funny is that o2 are offering "O2 is offering free damage & breakdown cover which replaces the manufacturer’s warranty when it expires and ensures customers are fully covered for two years." then on the next paragraph about cracked screens and making claims "Customers will only need to pay a £55 excess for each claim." So i'm assuming it's not free cover?
Yep, it's not uni days you just show them your uni ID instore. Link here: http://www.o2.co.uk/studentoffer
