Upon upgrading my iPhone from 3GS to iPhone 4, I notice blazing 3g speed. I've actually gone from 800 download / 300 upload to 4500 download/ 1300 upload. Nice. Yet even though the iPad has the same chip, my speed is 700/250. Sure, there's more RAM in the new phone, but that can't account for that kind of speed increase. Is this purely a function of the 4.0 software? Anyone else's iPad seem now painfully sluggish? Do we think the upgrade to iPad 4.0 software in, sigh, November, will make this wonderful device zippier?
