Wow! I'm a light weight. 461,368kb.
But honestly I've been using a lot of Wi-Fi. While my Pre didn't have enough *** to utilize Wi-Fi the Evo smokes with it. A test today clocked over 10000kb/s.
I noticed no difference between 3G and Wi-Fi on the Pre and left it mostly on 3G.
So far, I have used 4,034,216KB since June 9th. I am using unREVoked and Wireless Tether. I have an iMac and Macbook and Lenovo running Linux Ubuntu. I am a high bandwidth user and am able to only connect to Sprint's 3G network.
So, I love my Evo and would not consider the limited AT&T usage for the iPhone although it would seem to be easier for me to get another Apple product when syncing up my iMac and Macbook. Using Double Twist was so easy and transferred my iTunes with no problem. Go Android APPS!! But, I have no regrets and love my Evo. I would not recommend using LetsTalk.com as I have had really bad customer service, or I should say, non-existent service as no one replies to my emails.
