A few weeks ago Apple released the iPhone 2.1 (1.2.1) software update. I have noticed a big change in signal strength and overall stability, I also like the way the new 3g icon looks. There aren’t many changes to the GUI except for the 3g icon and the Genius feature. If your fed up with the bugs in 2.0.2 the just upgrade to 2.1. You can also Pwn your 2.1 iPhone with QuickPwn as PwnageTool will NOT work.
