Modem pulled from the Samsung Blaze4G.
Not hard to install at all, just put it on your sdcard and flash in Recovery.
Yes. This was not originally for Froyo I have to remove some /libs.
I made it work for the Sidekick 4G.
Credits to Master&Slave for pulling the Modem from the device.
Here is a link to get the KD1 and KJ2 modems. This is handy for people that want to revert back to what they had before.

On my device, the KD1 modem has delivered around 10 megabits down and 1.5 megabit up... KJ2 averages around 7 megs down and 1.5 meg up... This Blaze modem delivered about 3.5 megs down and 1 meg up.
I tested over a three day period with each modem. I have posted the best speeds that I see and they all come from the local test servers in Dallas. Speeds from New York and California have too many variables between me and the server to be reliable.
