Ok so I've read numerous posts on tethering and I would like to confirm some of the things I've read. I am going camping this weekend and would like to be able to browse the net on my laptop. I do get cell service at the campground with my HTC Aria 2.2. Can I use the new wifi hotspot app that was put on my phone with the update alone or do I need to use something like easy tether. I have HTC Sync 3.0 on my laptop and the Data Sync cable that came with the phone. I think I have the right tools to do it I'm just a little confused. I also read that ATT charges an extra $20/month for tethering???? (I hope that's wrong) I have the 2 GB Data Pro Plan.
