It's been almost 2 years since I last used an iOS product, my 2nd generation iPod Touch, so I am behind in what has happened in this field. Thankfully, I should be receiving my iPhone 4 for Verizon anywhere between Feb 3rd - 10th (if the pre-order goes as planned). Now I have some questions so I can start preparing for my device. 1) From what I understand the Verizon iPhone will be coming with iOS 4.3. Any word out if a jailbreak for this is in the works? What about iOS 4.2.1? Is there a jailbreak for it out? What if iOS 4.3 does not have a jailbreak upon release, can I downgrade to a previous release? Lastly, what is the difference between a tethered jailbreak versus an untethered one? 2) I saw a product called Powermatt, or something along those lines, that charges the iPhone without a cable - it works almost as a magnet? Is this a generally worthy product? Does it charge as fast as a USB charger or a wall charger? 3) Before I sold my iPod Touch I remember iTunes was developing a new feature that allowed you to view your applications and iPhone screen on your computer. Is this feature already implemented? How does it work on a windows PC? Does it work for a jailbroken phone? 4) Anything added to the music player since iOS 3.0? Any other hints for a returning apple enthusiast? Thanks!
