Auto Redial feature
One great thing I am missing a heck of a, lot in my old sony ericsson phone is the Auto Redial feature: if you have to redial a busy phone number, that feature automatically redials that phone number without any further step until the line isn't busy anymore!
If any great and talented developper could include that fantastic feature in our precious iphones, I know a lot of iphone users would be very happy and greatly appreciate that "must have and cannot live without it" feature.
Something that Apple should have included in the first beginning!!!!!!
this is basic feature in all mobiles!! other than the iphone
