I signed up before I knew much of anything about mobile internet and I can't believe how much money I've saved with the knowledge I've gotten from the newsletters and the forums.
I got in with Omnilynx before they shut it down and got a free hotspot. Then I was able to walk through the UDP AOL process myself.
I can honestly say that signing up to be an MIA has saved me over $1100 in the past 6 months and I'm sure the newsletters will keep me saving more as time goes on. Thanks guys for the awesome information source!
