Ok, I finally got my head messed up enough to figure out why the settings weren't working on the 5th edition devices. It's now fixed in 0.61. You can get the versions from the normal locations, 5th edition is at http://5th.mirggi.net/ from now on.
There are no major changes in this version, mainly the 5th edition compatibility and update to the Estonian translation (thanks Henrik!)
Oh, and naturally the certificate thingy is fixed. No need to change dates on your phones to install. Sorry for the delay :(
Text input on 5th edition seems "a bit" shaky, I'll try to fix it now!
