Hello,
Thanks for writing about Kindle Touch.
Kindle Touch 3G provides free 3G wireless that lets you download books right from your Kindle.
Using the experimental web browser, you’ll only be able to access Amazon.com and Wikipedia using the 3G connection.
Unrestricted web access is available only by connecting your Kindle Touch to a Wi-Fi connection.
Customer feedback like yours helps us continue to improve the service we provide, and we're glad you took time to write to us. The Kindle Team will carefully review your feedback.
Thanks for your interest in Kindle.
Thank you for your recent inquiry. Did I solve your problem?
