VZ Contact Transfer app available for your iPhone 4 to ease the transition pains
The App Store is flush with backup and cloud sync software, but this one might come very handy if you have used a non-smartphone device on Verizon before.
Just upload your data to Verizon's cloud via Backup Assistant, and let VZ Contact Transfer be the pilot app you install on your shiny new iPhone 4, in order to download your contacts to Apple's finest memory. There is just one user review for now, which claims that the app works as advertised, and that's all we want from it, really.
