RAR Decompress on iPhone Device - iphone

Has anyone found a solution to decompressing RAR files on iPhone (not Jailbroken)? It would be great if there was a library similar to libz.
I did not find anything official from RARlab.
Anyone successful with integrating unRAR into their app? The
source code appears to be C++?
I know that this has been asked before, but I've not seen a solution other than porting unRAR which is beyond me. Would greatly appreciate any information or suggestions. Thank you.

If you want to use the unRAR in an iOS app, you'll probably need to find someone experience with C++ to integrate it into your project.

iPhone FTP Integration

Can someone point me in the direction of an Objective-C (or c/c++) library, or tutorial (Objective-C) that teaches uploading or downloading via FTP? Preferably one that shows how to download a file to a temp dir, then upload it later? I don't mind one aimed at OSX, but my goal is the iPhone / iPad. I'm still googling, but the results are slim at best.
EDIT: This looks like it'll do the trick:
