I took advantage of the Black Friday sale on the galaxy s3 and ordered one on the Sprint site. I should be getting it sometime next week, but there's one problem. I added a line to get it, but that's not the problem. I wanna put it on my primary line, but I don't have a spare phone to put it on, and I wanna give my current one to my friend. Can I just have the line sitting there without a phone or do I have to have a phone on it? I don't mind paying for the line, but I was hoping I can get around this. Any suggestions are welcome. Thanks!
