Apple has released iOS 4.0.2 for the iPhone 3G, 3GS, 4, second-, and third-generation iPod touch, as well as iOS 3.2.2 for the iPad. According to Apple’s release notes, both releases patch a “security vulnerability associated with viewing malicious PDF files.” Apple recently came under fire for the security hole, which could result in a hacker gaining administrator access to the device. iOS 4.0.2 and 3.2.2 are available now through the Update function in iTunes.
Updated: One iLounge editor has noticed an uptick in reported iPhone 4 signal strength since installing iOS 4.0.2 software. Under 4.0.0, the iPhone reported 4-5 bars of strength, falling to 2-3 bars when 4.0.1 was installed. The same iPhone 4 now shows 3-4 bars of strength, suggesting that something may have changed again in Apple’s bar-displaying algorithm.
