Do you have an iPhone 3GS and a burning desire to fire up Backgrounder but no access to a PC? Well dry those eyes Mac addicts, as Geohot’s baby is now ready to go on OS X. Cohorts AriX and westbaer helped Geohot pack purplera1n into a tight little Mac OS package and it’s now available on the site alongside a new and improved RC2a version for Windows. Sweet. Standard disclaimer: we’re not sure how purplera1n and the ensuing jailbreak will affect your iPhone as new OS builds come out, so proceed with caution.
