The 1.4 beta of iNdependence was recently released. It allows for (nearly) one-click jailbreaking and unlocking of iPhones running 1.1.3 software. I tried it this weekend and it worked great and was pretty easy.
Things is a neat and full-featured todo manager app. It’s sorta pricey, though, and doesn’t talk to iCal, plus I was having some trouble getting my head around how I’m supposed to use it to be more efficient. Now I’m giving Anxiety a shot. It is cute, simple, free, and integrates with iCal and Apple Mail using Leopard’s built in todo support.
