Sell PCS maybe, but FON? no way. Dude, telcos make money on long distance even though they bitch about declining revenues. IMHO, long distance rates will trend up as the telecom mess plays out. BellCanada is raising long-distance rates by covertly sneaking in a hike on long-distance plans. Watch as long distance rates sneak up. No doubt in my mind this will BENEFIT long-distance "wireline" carriers like FON.
Wireless is a big unknwon. Sell that if you want to cut risk. Don't sell FON (it makes money!).
