Insanely in-depth review of the iPhone 4 online on Engadget. I suggest you to Instapaper it, but let me quote just a few passages:
“The iPhone 4 is the best smartphone on the market right now. The combination of gorgeous new hardware, that amazing display, upgraded cameras, and major improvements to the operating system make this an extremely formidable package. Yes, there are still pain points that we want to see Apple fix, and yes, there are some amazing alternatives to the iPhone 4 out there. But when it comes to the total package – fit and finish in both software and hardware, performance, app selection, and all of the little details that make a device like this what it is – we think it’s the cream of the current crop.”
On Bumpers:
“We’ve got a few bumpers in-house, and while we’re not really big fans of the way they look or feel, they do seem to protect the phone pretty well.”
On battery life:
“we managed to squeeze more than 38 hours – yes, 38 hours – of life out of a single charge using the phone as we normally would. We’re talking calls, some gaming, lots of push email and calendar invites, playing music over Bluetooth in the car, and just general testing (like downloading new apps, rearranging icons, tweaking settings). We went from 10:30AM on a Saturday morning till 1:00AM on Monday without needing to charge the phone. “
On FaceTime:
“Additionally, in our testing, we found that you really need to have a good, strong, nearby WiFi signal to hang onto a connection. More than once we had video freeze on us, and we had one fully dropped call because someone went out of the WiFi range, but hey… you need to be in range for even the most basic tasks, so we can’t fault Apple too much for that. It does seem clear that the iPhone video chats are moving quite a few bits around, however. What’s nice about FaceTime is that unlike Qik or other third-party options for something like the EVO, there’s no setup here and it’s completely integrated into the dialer of the phone – meaning the only hangup is whether or not you have decent WiFi.”
