I set up my new Treo 600 yesterday and struggled with getting Vindigo to operate.
First, it didn't copy over from my old Palm device -- the app went into an unsupported apps folder. But I reinstalled it afterwards.
The vindigo web site
http://www.vindigo.com says that it supports Vindigo for mobile phones, and has a plan with Sprint. $2.99 a month for wireless updates, but it doesn't list the Treo 600 as a supported phone.
No one at Sprint knew anything about it. None of the Tech Support guys had ever heard of Vindigo.
I finally got it installed, and updating using traditional Hot Sync.
I saw the "wireless sync" option on the "Edit Cities and Channels", and clicked on it, and now I'm having moderate success with wireless syncs, but it fries if there are a lot of updates.
Anyone else trying to use Vindigo with their Treo 600 and Sprint?
