Here is the firmware that I use:
Alternate WPDN Firmware: Modified OP/Stock Hybrid 11/19/10 & 1/11/11 - KG
It is a hybrid firmware based on the stock 11/19 and OP 1/11 firmwares.... plus the 2D/3D Graphics patch, ARM11 optimization and Google Experience and Android Market.
This combination will offer the fastest and most stable firmware/configuration currently available. (including true sleep mode) This is superior to the standard 1/11 OP firmware that I was previously using.
Yes, the original B&N store and reader software (actually all of the original PDN software) is included and works.
