I am asking this question bc I almost had to restore my iPad 2! Luckily due to the experience I saved my shsh through TU (thanks Leigh for the thread - although i had a dickens of a time trying the dfu, it went black but was not recognized on iTunes). Anyhow through trial and error, I uninstalled winterboard (themes etc were incompatible). BUT, I bought a couple of themes eg blueipad. So would it be ok to reinstall Winterboard so that I can at least get my $$ worth? Btw I am also the person who was trying to put an image on the status bar. I deleted all the files I created in ifile.
I love my JB iPad!!
