Today's How-To: Hack your N97 to run unsigned apps, among other things.
The latest version of HelloOX has been released, and it’s easier than ever to get unsigned software working on your N97. But let’s step back a bit: unsigned software is simply any kind of application that hasn’t gone through the Symbian Foundation’s rigorous signing process. Most freeware is unsigned, mainly due to the costs involved (around ~$525 for the bare minimum of one signing, with extra $$$ or euroseuroseuros for additional signing). With the included ROMPatcher utility, you can also apply unofficial patches to the firmware to fix bugs, modify current functionality, or adding new features. Pretty cool, right?
Unfortunately, by default your N97 (or any other recent S60 phone) will not allow you to install unsigned applications. We’re going to change that.
