There are two new ways to hack your Symbian S60 phones, first one is the popular HelloOX that just got a new version released. The HelloOX2 is an One step Hacking tool for all Symbian S60 3rd & 5th phone. Hacking mean that you can get unlimited access to your phone's system folders and files, with this capability, you'll be able to mod your system apps. for example: modding installserver to install any software you want, don't have to care about certificate anymore...
The second way is to get a certificate and key file to sign you unsigned applications. This way you do not have to hack your phone, but you need to use the signing process every time you want to install a unsigned application (usually takes 10-15sec)
