Yes, I love it. Here are my Facebook posts: I bought a extended battery for my BB Curve 8900, the phone has been on for over 27 hours, and still has over 75% power left. I likey. :-)
10/29...Phone has been on for 72 hours.......many phone calls, web surfing, and a plethora of downloads, emails and text msgs....extended battery at 65% charge....this was worth the cost
I bought the one for the Curve 8900. The phone becomes a bit thicker and heavier. It makes the phone easier to hold and text with my right hand and thumb, for me anyway.
