Monday's iOS 4 upgrade should have patched about 65 different vulnerabilities within the iPhone's operating system. However, the iPad may actually be susceptible to a number of those 65 software vulnerabilities. The bug count is actually a record for the iPhone, which far exceeds the high count of 46 bugs found in last summer's iPhone OS 3.0 update.
Computer World is reporting that iOS 4 actually included patches for 35 different bugs, which averages out to a total of 54% of the purported vulnerabilities fixed. Most of the patched bugs were actually issues with WebKit, the open-source browser engine that fuels browsers like mobile Safari.
That means that half of those bugs probably still exist within the operating system on Apple's older iDevices. Though it's unclear how many issues will affect devices like iPad, which runs on a different iOS version, it's important to note that some of the vulnerabilities that existed in the iPhone 3.1.3 update (which was issued in February) may still exist in the iPad's iPhone 3.2 operating system.
