I can get to Connect from my iPhone by going to http://www.gtdconnect.com and putting in my user name/password.
The IT team said:
There currently is not an iPhone mobile-like webpage for Connect. The web page renders as a normal web page and you can sign in and access it, you just can't watch the videos or listen to audio. Whitepapers, articles and such all show fine. Some iPhone users experience issues logging into Connect because the iphone automatically wants to capitalize the first letter in the password.
Is there any way we can listen to the audio/video portion of GTDConnect on our mobiles? I spend a lot of time on transit and would love to be able to listen en route.
Subscribing to the podcast feed for GTD Connect should give you what you your member content on the go, as long as your mobile device can support that.
