Thanks for this.
EDIT:
Installed, flashed the new modem.bin, restored from CWM backup, so far it's working beautifully. I haven't noticed any practical performance boost yet, but the numbers from Linpack, Quadrant and Neocore are pretty decent.
Linpack: 14.5Mflops (EDIT: subsequent runs show 16.5+ Mflops)
Quadrant: 1496
Neocore: 54 fps
This is a slight boost from EF02 with the EF10 modem, though I forget what the stats there said. To note, I am NOT on ext4, but my data card is a class 10 SDHC 32GB. I don't know how much that affects performance, but it sure affects file transfers over USB. I flashed the deodexed ROM with CWM 3.1.0.1 purple and the modem.bin with Odin. I haven't had a chance to test GPS yet; the GPS driver kept locking up on EF02 and I had to hard-reset the phone to bring it back. Hopefully that won't be an issue here.
