"Verizon is arguably the best in terms of coverage, although I'm surprised your Sprint MiFi had problems - when there's no Sprint signal, it should roam on Verizon's network. Then again, I had to turn on data roaming with my Sprint Palm Pre to take advantage of that. There was a firmware update for the MiFi's earlier this week (http://jkontherun.com/2009......) so maybe that's the issue? Regardless, if you're thinking of ditching both devices (iPhone and MiFi), the new Verizon Droid announced today should be on the radar. There are 3G tethering apps (although you may have to root the phone) and Android 2.0 looks stunning in terms of features and UI enhancments. Plus -- not sure if this adds value to you or not -- the new free Google Maps Navigation on Android 2.0 just trumped any other nav system by leveraging real time Google Search, street view and more. My $0.02. :)" - Kevin C. Tofel
