Former verizon Droid owner here. Recently purchased the verizon iphone and after 4 days of use I decided to return the phone based on the following observations. 1)Antenna issue. I noticed this the first day I was using the phone. At my office, I always had slow 3G service on my Droid because of the location. However, with the iPhone, my data service cuts in and out without me even touching it. And once I pick it up with my left hand, data pretty much cuts out completely. This is a big deal for me as i spend 8+ hours each day at work. There is also the same signal attenuation issue if you grasp it like the AT&T iPhone. And NO, this should not be expected as Apple had every opportunity to redesign the antenna since they had to use a CDMA antenna. This is simply poor engineering on Apples part and should not be rewarded. 2)Battery life - I believe this had to do with me being at my office. My droid had good reception on data as well as voice. But I noticed that the iPhone struggled to juggle both throughout the day as it continues to search for 3G and voice connections, my phone literally goes from 99% to 40% by 2pm each day I've been at work. This is with minimal use, no push notifications/data, and I tell the phone to pull email every hour. This is pretty terrible to ME, as I've been using my Droid with extended battery and get 36hrs of heavy use easily. 3)Notifications - This was something that was rather surprising to me. I thought that surely Apple would have placed some sort of visual notification scheme for email or messages on the phone as I keep the phone on silent through the day. However, the only way I even noticed that I have emails or messages is if a pop on the phone every so often. Compared to the Droid, I received various LED notifications the would signify email, SMS, or missed call. 4)iPhone 5 - I was pretty ready to let go of the Droid as I always felt that the Android OS was a compromise to me as I was stuck on Verizon and every other computing device I own is Apple. I also felt the Android OS was clumsy, not as intuitive, and most importantly, it just lacked the "Snappy" response that iPhones had. This was the reason I was so ready to jump on the iPhone 4 bandwagon. After my 4 days with the iPhone 4, I've realized that it was never an upgrade...more of a lateral movement and a slight step up. I guess I will see whats in store for Verizon come this June. If Verizon does not receive the iPhone 5 by then, iOS might never happen as I do believe Android is catching up with each new release.
