Jesus how hard is it for people to read posts rather than just pick out one or two words they like and twist
The logging in each time thing was IF you don't have the free wifi bolt on provided by most networks on iPhone contracts and some PAYG tariffs and would affect ALL wifi phone's and not just the iPhone (which the OP doesn't even have). Wetherspoons offer free wifi anyway through their cloud hotspots. But you'll need to create a cloud login and log into it through the landing page when you connect to the cloud hotspot. Its the same if you use a laptop, iPhone or an internet connected monkey! Of course the browsers in each of them (bar the monkey) can be set to remember login details but you will have to still click on login.
If you have the free wifi bolt on as psionic said you will need to login with your mobile phone number the first time you try and use it but after that you are good to go each and every time you connect.
God the Apple bashers are getting desperate today, if its not the antenna issue that affects hardly anyone in normal use, its an article that among other places has appeared in the daily mail (so there's scaremongering for you) and if that fails they'll resort to twisting words to suggest an iPhone can't automatically log into a cloud hotspot due to a quirk of the cloud that affects laptops or any other device using the free wifi service offered by wetherspoons pubs!
If it wasn't so hilarious as to what they are going to come out with next it would actually be rather sad
