I just jailbroke my 1G ipod touch 3.0. Using ICY, it won't let me download because of: "Package "mobile Substrate" cannot be installed (DPKG returned error #2)." in the view console log it says: dpkg: parse error, in file '/var/lib/dkpg/status' near line 26 package 'firmware': duplicate value for user-defined field 'Name' To fix this problem follow the following steps: Assuming you jailbroke 3.0 with redsnow 0.7.2 and chose to install both ICY and Cydia. 1. Re-run the redsnow except this time ONLY check the install Cydia. Leave ICY option unchecked. 2. Follow the instructions given at each step of running redsnow (the "3rd" part when it tells you to hold the home button for 20+ seconds, i just held it the whole time til it said finished, i dont know if that makes a difference, but it worked for me) 3. when it reboots, you can use Cydia and ICY will still be there. 4. If ICY doesnt work yet, same error, download Winterboard from Cydia, and it should be fine Hope this helps!
