So I am wondering--if I buy a cheap Android phone and root it, but don't have a cell plan attached, isn't it basically an iPod touch? I have wireless at work. I've seen LG Optimus "S" phones going for nothing on Ebay, like <$25. I'm wondering what cheap Android phone would work for the following: 1. Basic calendar 2. email 3. bike gps unit 4. listen to music Or do I need to have a cell plan to use the GPS? Thanks.
