(This would also benifit users by cacheing both upgrade and restore SHSH blobs to sauriks server so users aren't stuck with only being able to upgrade or restore.) -o) Also img3 should be updated to be able to fetch tags from each image such as the VERS tag to be able to compare with the current iBoot version. -o) Many of idevicerestore options can probably be compiled into one flags structure. -o) Need to add 8900 file support into img3.c. -o) Cacheing TSS and activation info locally so the program doesn't need to query apple/cydia servers everytime would be nice. -o) Need to add support to handle and display status messages correctly. -o) Writing restore logs to an external file for debugging would be a great help. -o) Need to change some info progresses to only display the component name rather then the full path which can be messy. -o) Would be nice to add options to keep some connections open during similar operations rather then reopening and closing them each time. -o) Extracting and signing all firmware files at one time rather then extracting and signing each one as we need it could speed things up as well. -o) Clean up restore_send_kernelcache -o) Clean up restore_send_nor -o) Finishing cleaning up asr_perform_validation -o) Double check to make sure asr_send_payload looks clean
