Following last week’s appearance of the first third-party native iPhone application, developers have continued to pursue the building of new, unsanctioned programs for the device. Erica Sadun of TUAW has built both a voice recording app, VRecord, and a screenshot utility for the iPhone, and a native NES emulator, iphonenes, has appeared on Google Code. A video of the emulator in action can be found on YouTube. Unfortunately for most iPhone owners, installation of these and other upcoming applications still requires a “Jailbreak” of the device. iPhone modification programs such as iFuntastic — which recently added file browsing in version 2.5 — are making the process easier for the average user, but modification remains an “at your own risk” endeavor, and it is reasonable to assume that any future iPhone software update may override any changes you make to your phone.
