Extended battery without seperate case

[shezzy]

So I am getting the S2 soon and was wondering if an extended battery was available that didn't need a seperate back case.. Kind of like this

I had this from my transform ultra which works slightly better then stock..



ALSO, Is there any extended batteries which might require a new back plate but also have a protective case for the whole phone?

No way am I using a $300+ phone without some kinda of casing on it but I would love to also have an extended battery..

Thanks!!

I would like an extended battery if it could be the same size as OEM battery. What I would really like is to have a Powermat induction charge battery.
