Yes, I would. The ebay market for a new S3 is around $425 and probably a little less on CL depending on the local market. Your etf is going to be $200 per line so $200 X 5 = $1000. If you sell the other two you can almost cover the cost of the the $1000 ETF. Even if you sold the other 2 on CL for $350 a piece that would put you at $700 and the remaining cost of $100 per S3 plus the time you had to keep your lines active to receive the rebates, but its not like you wouldn't be receiving phone service during that time.
