This post is for anyone who took out an o2 iPhone 3GS contract on launch day, or near to launch day.
As you may or may not have been aware, it was cheaper in some cases to take out a more expensive contract (eg. £45 per month) to allow you to pay less for the handset (£100 cheaper on a £45 compared to a £35 per month contract), and then downgrade after 9 months.
(Effectively saving you £10, but giving you a hell of a lot more minutes for the first 9 months).
Well, it has now been 9 months since you took your contract out (Yesterday if you took it on launch day), and as such you are able to downgrade your contract.
You may also know that the tariffs have changed, and are now in £5 increments, so if you are on the £45, you would have to downgrade to £40 this month, and then £35 next month.
I used the argumentthat when I took out the contact I was told that I could downgrade to £35 after 9 months, so after speaking to a supervisor, they agreed.
I'm now on £35 a month, saving me £150 over the remaining 15 months of my contract.
Be aware, that it isn't just the prices that have changed with the new tariffs.
On the £35 a month, you still get 600 minutes, but get unlimited texts instead of 500. The downside is that you have to pay for international texts and picture messages (used to be taken off your inclusive bundle).
