Goozy, Sprint discounted the Premier program last year, No one gets the yearly upgrades any more, It is either at 20-22 months depending on when you last upgraded.
I feel kinda bad... I've been happy with Sprint all along and wanted to go from EVO to IPhone5 in October... especially happy with the unlimited data.. unfortunately now that they are outsourcing their jobs overseas I cant see myself sticking with them.. putting Americans out of work at this point in time and Sprint's customers being 95% American based is kinda like a kick in the American workers teeth... I'm going to do some research and move on I think.. I'm actually a 26yr VZ employee who will not subscribe to ANY of their products and services due to the same thing... just not rite...
Sprint's outsourcing is old news! Most big American companies have been doing this for years! I sold my iphone 4 because of Apple's labor practices! The exploitation of chinese workers so Apple can make billions off of us! Chinese workers have been known to commit suicide over labor practices simular to Apple's! Sprint is always hiring american workers in the US stores and apple too but Apple is the biggest exploiter of people!
At this point, I would wait. However:
If you upgrade right away, true, you'll not be able to use any planned 4G, but you will be guaranteed that all current apps will function when downloaded from the iTunes App Store
Regardless of your path. any Bluetooth devices should continue to work unless the OS alters communications protocols. Bluetooth hands-free devices are now required in many states, so it's worth the mention.
Sprint is not going to sell the iPhone 5 on September 12th: September 12 is just part of advertizing or pre sales. No actual phone will be sold.
