I've had my iPod Touch jailbroken for about 6-months now and, I know this will be an unpopular statement here, but I really haven't used any of the jailbroken functions all that much. And find myself getting more and more applications from the standard store, taking up space. So with the new firmware released from Apple, I was thinking of going back -- at least for now -- partly to reclaim some of that space from my 8 GB iPod (regretting not getting a bigger one). If I just upgrade the firmware, I know it will un-jailbreak it, but will that space be reclaimed? Or do I need to manually remove folders, etc.? Basically, what's the best way to do it.
