No live wall on the iPhone, unless you want to jailbreak, but it would only let your iPhone act like an android, which is poor battery life and lag. My opinion, even if you do jailbreak, stay away from it.
I agree. Makes the phone too laggy no matter which iPhone you have. Hey Benny! Sent from my iPhone 4 using iCafe app
I'd love to have a live wallpaper, but it's not worth the battery sacrifice and I won't jailbreak my phone. I'll stick with the gorgeous artwork that's available and just switch them out when I want a change. I look out the window when I want live wallpaper! lol
I have used several from Cydia. It didn't really hurt battery much. No more than playing a game and surfing web.
