Im guessing you didnt have to trade in your phone because you didnt have to pay contract price for it. Im also guessing you are probably one of the few who buys their phone straight up, which made you exempt from having to trade a phone for the One Up Program. Now it wouldve been super cool if you managed to get them to let you keep your phone and still get into the program (which is what I really need altho I got my phone at contract price) and here is why.
Last year sometime, I got the S3. The rep who sold it to me didnt put insurance back on it, I just learned not too long ago that I've been without insurance for over half a year. My S3 is bugging out, and I need/want the N3 (but I dont want to give it up cause I can still use it for other purposes). Since my phone isnt insured, it looks as if I need to find a cheap phone and put that on my line to hand it over if i must give up a phone, but I read that Sprint has caught on to this and ending the quick swap.
I also have a question about the One Up program as well (for anybody). If im forced to give up my s3, and take the n3, I have to pay the $350 in 12 months to upgrade to N4? Or, do i have the 12 months to pay the $699 before i can upgrade to the N4?
