Installous, for non-iPhone techies, is an application that, when loaded onto a jailbroken Apple smartphone, auto-searches across the internet for cracked versions of iPhone apps and allied software.
Jailbreaking, meanwhile, is the process of unlocking a smartphone or tablet computer from the vendor's lock-in, allowing any and all software to be run on the device.
The existence of Installous, which was coded by the Hackulous dev team, has reportedly put a lot of Apple iPhone software developers noses out of joint, on both sides of the iTunes/Cydia divide, as cracked versions of their software do not generate them any income.
According to the Torrentfreak newswire, one of the key iPhone and iPad jailbreakers - Stefan Esser (aka i0n1c) - has been releasing some of the most innovative jailbreaking software seen so far.
And now, says the newswire, he is considering adding a digital rights management (DRM) module to the jailbroken version of iOS5, which is under active development by his team.
If true, Infosecurity notes, the move could be a body blow to users of Installous, as it would effectively lock them into iOS 4.x until such time as other coders come up with a jailbroken version of the upcoming new iPhone operating system.
Given that Esser is the only dev team - so far - reportedly working on a jailbreak for iOS5, this could be a serious problem, Infosecurity notes.
And as you might expect, the dev team behind Installous are not exactly pleased with the gameplan, with the TorrentFreak newswire quoting them as saying it is a really bad idea.
"The entire premise behind jailbreaking is that you're able to do whatever you want with your device. It's your device, you own it and you should be able to manipulate the software in any way that you like", Hackulous admin Dissident told the newswire.
"That doesn't necessarily mean everything you do with it is legal, but that the manufacturer of the software and the hardware has no place in telling you how you use the device", he said.
"If a jailbreak author decides to add [his own] DRM to it, they are being extremely hypocritical", he added.
Interestingly, Dissident went on to tell the newswire that the jailbreaking industry is opposed to Esser's DRM plans for the jailbroken version of iOS5 and "a small army of reverse engineers" would appear, apparently ready to crack the DRM feature of Esser's code.
Until the gold code version of iOS5 appears - probably this September when the iPhone 5 and 4S models are due to be unveiled if the rumours are true - quite what will happen remains to be seen.
One thing is for sure, however, and that is that Apple's iOS5 development coders will be watching the Esser vs Dissident saga very closely indeed.
