Hi All I have compiled the pjsip for symbian S60 3rd edition FP1.Few days ago symbian_ua_gui.sisx file was working fine on the device but today When I try to install the self sign symbian_ua_gui.sisx file into the device, I am getting the "update error !". I have uninstalled all the previous application from the device but still getting the same error. I have also set the device clock time according to my system but getting the same issue. Please suggest me some solution. Thanks in Advance Regards Amit -------------- next part -------------- An HTML attachment was scrubbed...
