Sometimes you just need to make a quick little change to the file system, and you don't want to have to use your desk- or laptop to do it. On 1.1.x there was a solution: MobileFinder. Unfortunately, the authors never ported it to 2.x. Instead, they built a version for the App Store and are selling it. The only problem: that copy is sandboxed to its tiny little folder and can't do anything reasonable on the system (thank you Apple).
At some point I (saurik) noticed that the old MobileFinder was open source, and have been spending time porting it to 2.x. Here are the results of my labor. I doubt it fully works, but it seems to mostly work.
Please understand that I'm not the author of MobileFinder and don't really want to be in the business of improving it, but if there are any regressions from MobileFinder on 1.1.x I'd love to hear about them.
