I am trying to get to a website on my sony s1 tablet (Tesco.com - online shopping; bringing the supermarket to you.) but it is telling me it is unavailable. I can get to it via my pc and also my desire hd. The other strange thing is that I downloaded the Tesco App and it works (ie getting shopping lists and delivery times etc) apart from the checkout process which fails. I opened the app on my desire hd and it worked fine.... I have cleared cache, history etc and restarted but still no luck. Any ideas?
