I am using the $25 tethering plan myself. I have my N800 paired with my RAZR and have never had a moments problem with this setup in 6 months of use. I did not need (and did not purchase) the quick link mobile software. I simply set it up using DUN from the N800. I have never used axcess web. I figure that with the tethering plan and the N800, axcess is redundant, not to mention far less capable.
