Today was my first full day without Cydia. I had used Pwnage 2.0 in Simple mode, which installed Cydia by default. So why remove it? Well... from the get go I was disappointed in the performance of 2.0 on my 1st gen iPhone. Scrolling through contacts was slower, the normal animation (opening/closing, scrolling apps) was sluggish, holding the home key down had trouble killing apps as normal. Something was wrong. But what was it??? I had no clue. Was it the Pwnage? Apple's firmware? I pwned the phone a few times to see if there was any difference, but nothing Plus my iPhone had been unlocked & jailbroken since day 1 and I never had these types of performance issues. The one thing I did notice was that Cydia was the worst performing app. Coming from Installer, I wasn't surprised that it froze because Installer did the same updating all its sources. So I wasn't sure if it was really the cause of my problems. Last night I decided to re-pwn the phone, this time using Expert mode and unchecking Cydia. Guess what, it's been running like a well oiled machine for the last 15 hours! If anyone is experiencing some of the problems I had, you might want to try uninstalling Cydia if you don't need it. I'm sure I'll re-install Cydia again once things are a bit more stable.
