Just to get it out of the way: I have tried all of the usual settings solutions for dealing with certificate errors, ie: setting "all" applications allowed in app manager, online certificate check to "off", and monkeying around with the phone's date. My problem is that for a majority of software that is supposedly supported on my phone (Nokie 6120) I get the good old certificate error when I try to install. It does this for .jar, .sis, .sisx, everything. I have gotten a few things installed, but this is driving me crazy. On top of that, symbiansigned.com won't accept any of my email address for registration, so its not like I can even attempt to sign my own apps.

Anyone have a problem like this? Any other ideas for solutions? Thanks.
