Hi, I'm about as nubie as it gets using PDA's. I tried following the instructions here to use my Q as a modem. I d/l at&t connection manager and set it up. It recognises my phone and GSM network. But, when I try to connect I get error 734. I have unlimited data usage so I called AT&T. They said I have to purchase a seperate plan to tether. Is this right or is there a way around buying an additional plan?
