Coming from an iPhone4 running iOS6 (Jailbroken), iOS7 is a big leap forward for me. There are quite a number of features now which makes the need to Jailbreak much less. Here are some things which I find cool:
1) Better multi-tasking. I like the running multi-tasking screen which is so much like webOS “cards” and you can call this up with a double tap of the Home button (or the virtual Floating home button if you have set this up in Settings > General > Accessibility > Assistive Touch)
Like webOS the cool thing is you can swipe up to close a “card” and with two fingers you can close more than one card at once.
2) Siri works, seriously. I think many are under-utilizing Siri which can do nifty things like hands-free checking and replying or sending text messages, checking email etc. I am a heavy Rememberthemilk.com and I like the way you can use Siri to set your reminders .
3) The ability to block calls.This one I really like as I was missing the functionality of iBlacklist which requires a Jailbroken device. Now with the combination of iOS’ “Do not disturb” function and the ability to block individual callers, I am a happy camper.
4) More swiping goodness. It could be better but at least now in certain apps swiping can take you back or perform some functions e.g. trash an email.
