http://www.boxwave.com/products/highcapacitybattery/electraspan-high-capacity-extended-battery-t-mobile-g1_3283.htmThinking about maybe getting this it is a 2400 MaH and the battery case isn't as bulky looking as the 2300 one. i have the 1600 MaH ordered from Fommy.com but it is on backorder. Be aware that fommy.com has been saying things are ready to ship when they are on back order. It happened to me and i read several other reviews where customers claimed the same thing. I might just buy this one and sell my 1600 MaH when i get it.
