I haven't written much about it until the chickens came home to roost but if you are looking for 4G, the future is cloudy.
More at http://licensing.fcc.gov/cgi-bin/ws.exe/prod/ib/forms/reports/related_filing.hts?f_key=-216679&f_number=SATMOD2010111800239 and many more if you go looking.
The bottom line is their may be no 4G as we know it or they will live with dead GPS units.
I don't want to buy a Blackberry until they get little faster. I donot like the touch screens. Want somethng I can punch buttons on.
