O2 UK gradually rolls out iPhone unlock, forgot to give us the instructions

Last week O2 UK announced that they will start unlocking iPhones while they lose the exclusivity deal with Apple. We signed up straight away (via the link below) and didn't hear anything until today -- just five days after O2 unlocked the first batch of iPhones, according to tweets from fellow users. As you can see in the picture half of our text message from O2 went missing for some reason, but luckily the procedure was easy enough for us to decipher: simply put in a non-O2 SIM card, then connect to iTunes and boom! You can see all this illustrated in the gallery. Sadly we're stuck with O2 for another twelve months, but are there any UK folks here planning to switch carriers soon?
