I am just wondering if it is worth the upgrade as we are getting close to the launch day of iOS 6. The things I am afraid of is will it make my iPod 4g slower? And also will it use up more ram and cause apps to crash more often? If these things are true; I don't think I will be upgrading as none of the features really impress me like iOS 5 did. I don't have a developer account so I am needing answers to these questions please before I think about upgrading. Thanks.
