Hello! Got my iPhone 4 (upgraded from my 3GS)...not jailbroken. I do miss some of the tricks I had with Cydia, and I'm not sure if they exist in some fashion on the iPhone 4 or if there's a specific app i should search for. What I'm looking for.... 1. An app killer/ability to manually shut down unneeded apps in memory (FOUND...inherent in iPhone 4) 2. A way to toggle airplane mode WITHOUT having to go into SETTINGS to do it. I live in a rural area with no reception. I save lots of battery power by going into airplane mode when I get home and turn it off when I get back to town. In Cydia, Activator gave me a way to custom set many functions, and I had double-tap time on the lock screen as my shortcut. I'd just like a way to get this shortcut back without a tethered jailbreak. 3. Does the iPhone 4 have options to respring/reboot in addition to shutting down? Is there an app to introduce this function?
