What are the options for tethering an android tablet via an android phone (droid x). I have easytether on my fun, which works great for a my laptop, but if I understand correctly it will not work for tethering to another android device. Is this correct? I'm thinking about getting an android tablet but don't want to pay for a 3G plan. However, there will be times when I want internet access but a wifi network is not available. Any suggestions?
