OK, I am growing tired of this. First person to come up with a plist hack to disable persistent wifi, will get a free surprise (it won't cost much, but it will be good I promise). I say plist, because I have turned everything off, push, notification (individually and via master trigger), location services, mail fetch, calender update thing, etc. However it won't turn off. Restoring to DFU only works for 2 days before the problem resurrects (I thought it was an app, but I tested each 1 by one with no avail). Hence, the race is on, figure out a plist hack (particular to iOS 4 ipt 4g, be the first to post it, and get the surprise!!! ****Update**** Ok in all honesty, none of the suggestions bellow gave me a definitive fix for the issue. However, thanks to iBricked, I was able to figure it out. As promised, I will be giving iBricked a surprise. Unfortunately, I cannot render a lavish gift at this time, and as such, will be giving iBricked a $5 amazon.com gift card (give me about 5 days Señor iBricked). ****Update 2 (11/4/2010)**** iBricked has been rewarded. As for the Fix: ***This requires you to jailbreak your iPod and use SHH or iFile*** Navigate to: /System/Library/LaunchDaemons/com.apple.apsd.plist ... and delete: Code: <key>keepalive</key> Finally, reboot device.
