the multi task function does not spark at all you can't customize it like the JB apps "backgrounder" I wish i could choose which apps I want to run in background and which is not instead put all apps in background after pressed the home button

i just backup my contact using itunes by the way even if you didnt set the contact sync option itunes still backup your contact when doing backup

seriously the multitask implementation is lousy for me I'm on iOS4 iphone 3g i still dont like the fact we can't customize what apps want to be multitasked who the hell want the camera apps running in background apple should put some sort of method to close program without going to background instead of forcing all apps to run in background when the home key is pressed

just my 2 cent other work fine! even my digi 3g work w/o any extra configuration (maybe it get the old config from itunes backup) because internet/mms just work after restore

I downgraded back to 3.1.3 safari keep eating memory even with only safari running it using almost all the memory only have 5mb left. and when surfing + ipod it hang to dam slow
