true...last time ios4 update not like this, but nevertheless after successful update everything is ok, now i keep playing with all its function..really like the notifications a lot and twitter integration

Most important thing is always backup backup backup.

Went very smoothly for me, but hearing reports of little headaches here and there, maybe because major OS update.

Just as a reference, a pretty good write up here about anyone who may have lost contacts after the upgrade (Hint, in some cases, your contacts may not be lost at all, just not finished syncing yet):

yup very grateful indeed...still remember the countless backup i made and countless pressing of update button just to get verified from the apple server....seems like no pain no gain

Agree with people here. iOS 5 is a brilliant update, not due to any one big change, but the hundreds of little ones, making this OS feel so much more mature. Love these new features:

Notification center
iMessage (use it a lot with my family)
Reminders (use this a lot too)
Camera button and also camera access straight from locked mode
Assistive Touch, save home button clicks
From your camera, you can now swipe to your camera roll
Calendar - in day view, you can swipe for different days
iMessage - you can Facetime your iMessage contacts directly from within iMessage

Oh and my absolute favourite, Reader feature of Safari. I like to email articles to my family, and not just links, cos they malas to open. Sometimes a hassle to cut paste.

Now, like in desktop Safari, Reader feature is here. Try and load any article online, or blog or whatever, once fully loaded, "reader" button appears in the Safari address bar. Click it, and it will just take the pics and text, and get rid of advertisements etc. You can then email directly from there.

the Assistive Touch works like a shortcut button.

Looks like there is many problems for iOS 5

Try holding the home and ON button for 10sec.

iOS 5 takes more space compared to iOS 4. There's nothing wrong with your phone.

It won't keep decrease until empty. Most likely some cache file being downloaded by the OS. There's nothing to worry about.

Worst come to worst just do a restore of your firmware.

my ios5 keeps on crashing and restart itself into lock screen.... the most recent case happen today when i was listening to mp3 and the song started to jerk and then the phone just crashed and restart to lockscreen mode...

any idea?

if ur phone is jb maybe some tweaks or apps not compatible with current ios....

i got this low memory issue too ... and sometimes my icons become blank... thats weird ...

Ios 5.0.1 released public.
Fixed battery life.

Just did a update .. over-the-air through wifi .. everything went smooth.

updated, so far so good though .. cuz i din experience batt fast drain in ios5 ...
