I'm on 3rd Rant so far. The first two failed within 30 days, so they sent me new Rants. After a major software update, Rant #3 seems to be ok, but still messes up when online. It freezes up a lot and I get too many http errors. Oddest thing it does, when I go to a racing forum bookmark, it will either say the server is busy, or goes to sprint26c.sprint.aopmv.com, yet it shows the racing forum page with that address. Sprint must have an oversupply of Rants, since they seem happy to keep sending me new ones.
