Things I would like, but won't get:
Automatic app updates.
Move spotlight to Notification center.
1/4 and 1/2 size apps for ipad for multitasking opportunities.
Option to hide or remove some stock apps. ie; newsstand.
Folders that can fit more than 12 apps.
Live icons. ie; weather.
3rd party notification center widgets.
Some offline siri data so it doesnt always use the internet.
Huge, mainstream icloud integration.
Safari ad blocker
Explain "other" space better
Wish list in iTunes/app store
+
Set Default apps
Data usage monitor
Wi-Fi Direct support/Airdrop
Multitasking gestures - Zephyr
Camera app needs Timer, time/date/location imprinting, stabilization shot, 720p @ 60FPS recording option, White balance, Exposure, Light sensitivity(ISO), Contrast, Sharpness, all of these should be added.
Maps - Drop more than one pin on the map, routing between them
Delete photos from Photo Library, being able to view file information in photos (say date of taking etc)
iMessage - Needs an ability to share location(Map) like with WhatsApp, right from the iMessage. Current you can only send photos from iMessage, but Maps and Contacts shortcuts should be added too. Also it would be great if the image EXIF data was preserved when sent so the receiver could "open" that image in Maps and navigate... quickly snap a picture of a location, send it, the receiver gets the image, taps "Open in Maps" and finds the route to you.
Prevent shut down when the phone is locked
Delivery notification for normal SMS messages
Snooze time configuration option for alarm, (amount of snoozes, time in between)
Calendar event badges on calendar(with an ability to adjust how far in advance you can see your events, 24hours, 7 days, 14 days, etc..)
Birthday's in Calendar - show how old is person is turning into
Pictures in the Notes.app
Safari - Unified Omnibar, Private switch IN Safari not in the options, Tap and hold the tabs button to show history
Smart Playlist creation on the iPhone
