Sprint.com allows you to switch to an alternate phone now for SERO?

I'm sorry in advance if this is off-topic....but I just logged into sprint.com and they made me change all of my usernames and passwords and they have a new look now. I heard before for people not on sero you can add/remove different phones and I always wanted to be able to do that (I'm a GSM guy at heart and I loved having a smaller phone to go out with) so I'm just curious can we do that now? I see an option to "Upgrade or Activate Phone" then when you click that sub-options come up to "Activate it now" where you enter the IMEI. I'm just wondering if anyone knows whether or not we can flip back and forth between different phones. That would definitely take some strain off of my Mogul. TIA if anyone knows and sorry again if it's off-topic
