I'm in the market for a new Verizon M9 and both eBay and Amazon have a fairly limited selection. So, I'm wondering if I could expand my search to phones made for another carrier. I've done some searching and I haven't been satisfied with what I've found. I've read a few threads from various forums here and there that discuss it but come to no conclusive answers. The bulk of what I've seen talks about Sprint phones being compatible on Verizon. But again, a lot of back and forth and no real consensus on yea or ney. Can someone help me out? Are they compatible and if so, what has to be done (if anything) to make it work? Thanks.
