New day, new app in Cydia: Synchronicity. Synchronicity gives you the option to use your device during an iTunes sync. Instead of being stuck at the lock screen while you transfer new content, you can unlock, run apps, make calls etc.
You can do whatever you want, except run the Music app which is disabled during syncs to prevent data corruption. Though overall performance is virtually unaffected, you may notice sight lag in certain resources/CPU intensive operations.
NOTE: Synchronicity works on any iOS device running firmware 4.0 or 4.0.1
You can buy Synchronicity from Cydia Store for $2.00 via BigBoss repo…
