I have installed preware and homebrew apps with no issue but as soon as I install the tweak LSdiff and GNU I start having major lag. The phone app takes 30 seconds or more to load along with many others factory apps. I have done a full erase, I changed my profile, doctored to 1.2.1 and then up to 1.4. All is well until I try to install any patches. Any help would be appreciated.
