If I have another Sprint branded phone that has a clean EISN, etc. etc., can I activate it on an account without extending my contract or affecting my eligibility for an upgrade. I understand it can be done on line now.
I basically want to be able to downgrade from a smartphone to another phone that has longer battery life for use when I will not have access to a a way to recharge. (And yes I know I could carry one or more spare batteries.)
When I am back to having good access to a way to recharge can I swap back? is there a limit to the number of times I can swap? (GSM with sim cards is so much simpler.)
You can swap all you want between non-smart phones but remember that there's now a required $10 fee for smartphone use on any smartphone activated after March 1st, 2011. So if you're already paying the $10 fee then it shouldn't matter. Be careful.
