QuickPull v2. It simulates a battery pull. You can set it to work daily. Mine is set for 3:30am.
BigTinCan BuzzMe. Enables your BB to vibrate while it is ringing. You have probably noticed that BBs will vibrate first and then ring but won't do both at the same time. (This to me is the worst thing about BBs. Not being able to ring and vibrate at the same time).
Both apps are free. QuickPull is essential IMO.
