if you arn't jailbroken, its much slower than Safari due to Apples control, but if you jailbreak theres a tweak called Nitrous that enebles Chrome to be as fast as Safari. But the interface is much better so its faster to use too
nice, and yeah fuck winterboard, I only download the most essential tweaks I need (zephyr, NCsettings, Nitrous, etc.) to keep the battery lasting a full day. I really hope the 2012 iPhone has significantly better battery life than the 4s
