What does what mean? Getting an upgrade to 4.3 or buying at BB vs Amazon or something else?
I'm going to guess he didn't get the "flip" comment, so let me break it down:
Users on VZW with unlimited data, who (a) don't want to spend full price on a new phone and (b) don't want to lose their unlimited data can use a loophole...
(1) Start with another line on the same account -- ideally, a feature-phone line without data
(2) Assuming that line has an upgrade, use it to buy the new smartphone you want
(3) The line will be updated with a variety of new charges including a data plan (e.g., 2GB/month at $30)
wait a few seconds, then
(4) Move the smartphone OFF of that line -> it now reverts back to the feature-phone line with it's original plan
(5) Take your old smartphone off the unlimited line, and move/activate the new phone on it
I've talked to a few VZW corporate store reps who are happy to do this and my local BB is good with it too. Pretty impressive, as long as it lasts. The only downside is that you then lock the line you upgraded into a 2-year contract, but in my case that's a feature-phone line I'm keeping/using anyway, and it only costs ~$10 a month.
BUT THERE IS "ANOTHER" WAY. LOL I mentioned this in another post, but apparently VZW is quietly offering the Max plan WITHOUT the Edge plan which means: unlimited users also have the option to move into a 6GB/month plan for $30 (the Max plan) which presumably includes purchasing new phones on an upgrade at the subsidized price.
Sorry this all so far off topic. I hope it answers the "what does this mean?" question!
