I told you rfc2397 was good for offline storage didn’t I ? Here’s a program (source) that generates two bookmarks. Each of those are actually javascript programs customized with your PT-WIFI credentials. Bottom line, you can save these bookmarks on your iPhone’s Safari browser and once you have PT-WIFI coverage you’re one-click away to instant log on. No more clumsy, painful web redirects or forms to fill in. Very handy.
