From the "you can roam, but you can't hide" department, Brian Jepson repeats a way to bypass high STSN iBahn per-minute charges through Boingo: Jepson is at a conference that has 25-cent-per-minute iBahn service from STSN. This is the typical STSN rate for pay-as-you-go. Guests of the same hotel can typically pay a fixed day rate as part of a package involving phone service; or service might be free for guests.
Jepson hacks the system by signing up for an initial Boingo As-You-Go package of $7.95 for two one-day sessions. (This rate only applies for your first As-You-Go pass purchase, however; after that, it's $7.95 per day pass.) He then uses iBahn's extra options to authenticate via Boingo. If he'd had the Boingo software installed, he could have bypassed even more of the hassle.
