After a good amount of time being tested under a "beta" tag, Tether for Android has finally been released. While we all know that the tethering option does come included on some devices, Tether has been built in such a way that it works with all Android devices.
That's right, no Froyo is needed to be able to use Tether and no extra data plan is required from your carrier. You can use your already existing data plan with Tether and not have to worry about having another "add on" placed on your account.
As part of the launch celebrations, you can now get Tether for only $24.99 up until November 19th. After that time, it will go back to it's regular pricing of $29.99. If you want to learn more be sure to check out their website. [Tether]
