So I've been thinking of buying an improved battery for my phone as I'm going to take the dive into Napster soon and ditch my ipod altogether. I was looking at the SCH-i500 Fascinate XT 2200mAh Lithium Ion Battery, but also saw the Seidio BACY30SSFAS-BK Innocell Extended Battery. The only downside to the Seidio is that it makes the phone a behemoth, and I love the fascinate's small size. Any advice would be great, as reviews on both of those batteries are scarce. Thanks again!
