Few months back , I wrote post on how to sign and install unsigned Symbian applications . Due to two three months of inactivity and increased requests from my friends here , now I am again dealing with this topic . Like any Windows software, as security measure , the mobile softwares should also be digitally signed to ensure that its safe to install on the target device . Digital signing should be done by software authors or by the users . And in most cases , a certificate is associated with genuine mobile softwares .
There are 3 different methods to sign and install unsigned Symbian softwares .
1. Turn of the certificate checking feature in your mobile phone .
Go to your mobile phones' applications app manager and open settings . From the settings tab , select to install all applications ,instead of signed applications . ( Valid only for Symbian and Nokia phones)
2. Install unsigned Symbian softwares using developer certificates from Symbian.com website .
Symbian.com is place for mobile software developers where they get their applications digitally signed . Here you can upload your applications and download the signed versions that can be directly installed . But for registering at Symbian.com website , users needs their own own email address , that is something like username@userdomain.com . They won't accept Gmail , Yahoo and other normal email addresses .
3 .Sign and install mobile softwares using existing certificate and key file : The third method is uses a pre-created certificate and key file for local signing of unsigned Symbian mobile softwares . This method needs three things . A certificate file , key file and signing software(Signsis.exe) .
( SignSIS needs Microsoft .NET framework 3.5 that is to be downloaded separately )
If have a certificate and key file , as shown above, you can sign any Symbian mobile software using SignSIS . Use Password for key file as 00000 . Now if your want Certificate and key file for your phone , just subscribe to mobiclue.com's feed and then post your IMEI number and mobile phone information in comment box .
