I got an offer from Boingo today for unlimited wifi access at thousands of hostpots etc for $4.98 a month for the first three months ($9.95 after that) and you get a $25 dollar Amazon gift card after second month. I attached a screen shot.
Tip: I got the offer once and then it went away after I browsed to another page, so I opened up an incognito window and it popped up again.
That is all I know about this offer. I don't know anything about the service nor have I tried it.
Good luck!
