I'm a noob to all this smartphone stuff, so please bear with me. My last phone was a flimsy samsung slide up phone, so now you know what you're working with. I just bought the evo, and I LOVE it. I just have a question on that new Seidio 3500mAh battery. Is that the only expanded battery that is currently on the market, or are there other ones that are bigger that do not require a modified back plate. I was just wondering if there are others that are in the works that may be a better alternative. Also, i was reading that the new Droid X has stellar battery performance for a strikingly similar phone from some reviews on the web, and its battery is rated at 1540mAh. I saw a picture of the battery itself, and was wondering if any of you know whether it would fit in the EVO or not. I don't care much for the Droid X, but if its battery would fit the EVO, maybe that could help the cause. Just curious. Thanks in advance.
