HDR Camera Enabler is a new tweak available in Cydia that brings HDR camera feature to your iPhone 3G or iPhone 3GS. It is released when there isn’t even a jailbreak released. Download HDR Camera Enabler from Cydia ( available for free via Modmyi repo) and activate it in Winterboard. If you have an iPhone 3GS with older bootrom, you can jailbreak iOS 4.1 using PwnageTool.
