TLDR at bottom So the past few weeks my iPhone has been kinda sluggish. According to sbsettings, my available memory would get down to like 20 mb, and if i click the kill processes button and even manually close everything in my app switcher bar, that would just make it go up to like 80mb free. This morning I installed something and had to restart the springboard. When I restarted it, my phone "crashed" and went into a perpetual spinning circle tick animation. After 15 minutes of waiting, I decided to hard reset by holding down home+power. Phone went off, then I press the power button, and it takes a good 5 minutes of the Apple logo, then finally gets booted up. But now, according to sbsettings I have 290mb of memory free! And the phone is running like a dream again. Yet all the appropriate background apps are indeed running correctly (sbsettings, iBlacklist, etc.). So, in my long winded post: TL;DR - How do I really clear out my memory and get up to like the >250mb of free memory range where the phone runs really well?
