I think (my opinion) you should jail break your phone, install LockInfo and a notifier app. Just to see if you like it, if you dont its really simple to just restore it by plugging it into iTunes. You can have the phone jailbroken, apps installed, and un-jailbroke and restored (if you dont like it) in about 15-20 minutes (depending on the amount of apps and music you have on). I only have a few hundred songs so it doesnt take me that long to restore.
