I work for Boingo Wireless and am happy to walk you through setting up a Boingo account and ensuring it works.
Which Apple device are you looking to connect on, and what are your geographic requirements for connectivity, e.g., are you looking to access the Internet primarily in North America?
For Apple devices, we offer two options:
1) Boingo Wi-Fi Credits, which allows you to buy Internet access in one-hour increments: http://www.boingo.com/wifi-plans/mobile/boingo-wifi-credits. Each hour is $1.99.
2) Boingo Mobile, a monthly subscription for unlimited access on up to 2 devices with global coverage for $7.95 per month: http://www.boingo.com/wifi-plans/mobile/boingo-mobile.
Both apps are free.
The one common problem we're seeing among Apple device owners is that new hotspot networks must be first selected manually through the device's settings menu. This is only required the very first time you connect in a specific partner network, e.g., T-Mobile. After that, the app connects you automatically. More details here: http://bit.ly/hfE43d.Often, users are unaware of this extra step (which we're hoping Apple will ease since it's an API issue) and cannot login; thus, they think our service is not working.
Please feel free to reach out to me directly should you have more questions.
Boingo did not work very well for me. They promised that access to AT&T hotspots work. Well, although there were lots of AT&T hotspots scattered throughout the city I never managed to use one.
Furthermore the AT&T hotspot at my hotel would redirect you to the hotel's wifi meaning they would charge you the hotel wifi fee.
Not really what I had in mind when I bought a subscription.
It was rather slow at the various airports I tried it. Apart from that it will not show you any access points unless you are signed in.
