PSA: brilliant new mobile network

Has everyone heard of the new phone network, Giff Gaff?

It uses O2's network, so the coverage is exactly the same. I joined recently and am dead impressed. I had come to the end of my overpriced iphone contract and have just had my number ported over to Giff Gaff. For £10 a month I'm getting 250 minutes, unlimited texts and unlimited internet. Its SIM only so you just buy a package every month to suit your needs, the cheapest is £5 a month. I'm not locked into a contract now, and saving over £30 a month on what I was paying before, and getting a similar deal.

The only negative is that you don't get visual voicemail on the iphone (although the Hullomail app corrects that).
What's not to love?!

Here's the link, and if you get a SIM through this page, we both get £5 credit.
