I was revisiting this site out of curiosity to see if the Instinct has received updates from Sprint/Samsung and thought I should comment on this post.
Though the points you make MAY be valid they sure do not support your thread title.
I had the Instinct for 2 weeks and then returned it for the 3g which I have had also for 2 weeks. For me, all I can say is the Iphone 3g is WORLDS above Instinct in usability and speed. There is no real comparison....and the apps that I have been downloaded (only the free ones so far) have worked fabulously. One is a PHONE with some nice multimedia and I won't argue that Instinct's GPS is MUCH better and voice commands are sharp but the IPHONE is a true PDA. The Safari application alone is enough to put the iphone above the instinct.
All I know is that I can use my Iphone at any moment and know it will work for what I need. I couldn't do that with the instinct (except GPS)
Well good for you then stay out of this forum and go to a iphone forum, and i tried out the 3g my friend has it and he is returning it for a instinct on monday.
