I had reasons to change my carrier from tmobile to at&t. My wife has a iphone under contract and we need a family plan. I'm out of contract so I already grabbed a refurbished iphone 4 three days ago. I like my n900 and I'd like to keep this. But n900 is not compatible with at&t 3g and it's getting hard to find reasons I have to keep. I researched and if I sell my n900, I can get some profit. I know the final decision is mine but I'd like to get some ideas from maemo people. Should I keep this (for backup) or sell it right now before the price is going down?
