There is no reason not to try this VPN service on your android device. 500mb/month free with an extra 1gb each month if you tweet them. $4.99/month for unlimited. I've had no problems with their service.
This e-reader app allows you to store your books in your DropBox (or Google Drive as of v2.0), and then download them from there when you need them, with syncing between devices to keep your place, it's like a Kindle without the Amazon.
Well it's no secret that the Amazon Kindle is the biggest e-reader around, and if you've bought any e-books from Amazon you are going to want this app, there is no other way really to access Amazon's cloud that holds your books.
