Couple of questions

[ElAguila]

I see that not too many people are using the intercept. My brother in law just got one and overall it is a nice phone. It catches a lot of flack because the screen is only wqvga. But overall I like. Now to the questions. Are there any batteries from other phone models that are compatible with it or does it have a unique battery? Can anybody recommend a decent case for it? I have an innocase and holster for my hero but I didn't find anything like that for the intercept. And last does anybody know if the intercept has been rooted?
