I just jailbroke my 3G using QuickPwn and I understand that you have to use the "Manage" tab in Cydia to uninstall Cydia apps; however, there are a lot of apps in there that I did not install. Are all of those apps in there actually installed when you QuickPwn and, if so, what is the impact of having all of those apps on my phone. Do they take up a lot of space, affect battery life, etc? Other than the few apps I installed myself (Cycorder, SBSettings, etc.), do I need those other apps? Are they necessary for Cydia and/or the actual jailbreak to run properly?
