I know you don't believe your eyes but USB Loader GX v2 is out! A new channel is also out to accompany the new release. You can select to download the All in One Package, only the dol, the channel, whatever you want to do. The Forwarders page and the Downloads page have been updated with the new files.
Also cIOSX rev21 have been out for a while, but there was no official support back then. Expect a new post later today, or tomorrow with the new features for cIOSX and USB Loader GX. For now I'll give you only one thing.
USB Loader GX 2.0 supports ext3 partitions!!!!
