Apple's minor iOS updates seem to be coming thick and fast, with the latest rumor suggesting iOS 4.3.2 will drop within the next two weeks. According to BGR's source, the tweaked firmware will "include a few enhancements" though their exact nature is unspecified.
There'll also be some security fixes and and a range of bugfixes. iOS 4.3.2 will be for iPhone, iPod touch and iPad, though there's no telling what it might do to the recent untethered jailbreak the iPhone Dev Team has released. The likely suggestion is that users who want to keep their jailbreak should probably hold off from updating to iOS 4.3.2.
