Avantgo is a service that scraped websites and sync'd the content to your mobile device allowing you to read articles on the go. Effective June 30, 2009, they are dropping the service. I am actually surprised it is still around. It was neat to use when few mobile devices had online access or even lacked a real browser, but for several years not, just about everyone has full time all-you-can-eat data plans. The exact wording on their page is a bit strange:
"AvantGo is changing! From June 30, 2009, AvantGo will no longer be providing mobile content."
That makes it sound like the company itself will be sticking around, but doing what I don't know. They recommend you move to a product called Snac, but it requires Java and only works on some Windows Mobile devices. I used AvantGo as early as the late 90's with my first PDA, and in a way it is sad to see it go, but honestly I'd almost forgotten about it. I haven't used it for at least seven or eight years.
