I was due to have my iPad delivered today, so have stayed at home, but after speaking to TNT by phone about 5 minutes ago, they've just told me they've sent the shipment to the wrong distribution depot (Newcastle instead of Teesside), so it won't now come until tomorrow.
Same thing happened to me earlier today, but I got it delivered about 20-30 minutes ago. So hopefully it might still come, if not you'll get it tomorrow its worth the waiting for
