Enable iPhone 3GS Battery Percentage on iPhone 3G and iPhone 2G
Battery Percentage meter option is officially available on iPhone 3GS only running firmware 3.0 and above; however, there is a small tweak available in Cydia which can enable this functionality natively on the original iPhone and iPhone 3G running firmware 3.0 and above. You will need to have a jailbroken iPhone for this to work. Complete step-by-step guide for jailbreaking iPhone 2G/3G running iPhone firmware 3.1.2 can be found here.
Once you are done with the jailbreak, follow the simple steps below to enable iPhone 3GS Battery Percentage option in your iPhone 3G and iPhone 2G:
