I can't vote - I used Windows Mobile for... I don't remember for sure, but thinking it must have been 4-5 years? Then I got Windows Phone (Sprint Arrive) on the day it launched (3/23/11) after giving up on Verizon, but ported back because Sprint's coverage was horrible. Then I went to ATT after again giving up on Verizon and got a Samsung Focus, but alas, ATT isn't good here, either. I put up with it for a couple weeks, hoping I could learn to deal with it, and then Verizon made their announcement on 5/19/2011, and I had my Trophy on 5/26/2011, after more than six months of aggravation waiting on Verizon!
