Like you, I am a newbie and have only had my Tilt less than a week. One thing I found very useful was a free application called "
Live Search Mobile" which was free.
This allowed me to get driving directions from address to address or current GPS position to address, showed me traffic, showed cheapest gas prices around me, as well as a bunch of features.
This does what I need, so I bypassed the ATT Telenav.:approve:
Good luck!
