Hi All, I'm considering getting the X10, but I need to know if you have been successful in tethering w/ AT&T. I'm stuck with AT&T. My understanding is that AT&T wants to charge you an additional $20 a month to unlock tethering. I currently can do it on my Sony Ericson cell phone (non smart phone) using blue tooth, without incurring extra charges. This is something I use very occasionally, but is very valuable when I can use it. I still prefer my laptop for internet access vs. phone so the tethering has been useful at times when traveling. I still have the option of getting an Iphone, but must jail break it, in order to unlock tethering capabilities. I want to go with the X10, but I must first know I can tether without AT&Ts rediculous additional charges.
