Over on Sprint PCS Info we’ve covered in-depth the program BitPim. Basically, to wrap it up in a nutshell, BitPim is an opensource program that has reverse-engineered Qualcomm’s Brew Filesystem that all 3G phones with Qualcomm chipsets use. This allows people to install their own games, ringtones, and images to their phone, as well as backup purchased content (such as through Get-It-Now) to their PC.
BitPim is in a constant state of development, and we will keep you updated with the latest developments.
