Hopefully someone here can help. I have no problem installing smaller apps from marketplace at all, and plenty of space on both my phone and on my sd card. BUT if I try to install something larger, the installs error out (error 18, unknown) Sometimes I can put the apk on my sd card and install it from there, other times that still fails. This was occurring before soak, and I've completely cleared and reformatted my sd card, and also went from froyo to soak, and the issue still persists. The latest issue program is aldiko. I used to have it installed, removed it months ago, and now of course I cannot install it at all. Any ideas what I can do to clear this up? I'm pretty sure I did a complete cleaning of my phone for soak. Help!
