How to track down iOS 5 bug?

There's this post from ios-blog.co.uk which talks about how to handle bugs that are specific to iOS 5 which you might find handy.

We had a similar issue the other day at work for a web based application which if the field type is set to "text", for customers using mobile safari browsers with iOS 5, strangely all leading zeros will be automatically truncated. Have to put in special code to detect browser version and then change the field type accordingly.

Cool! Face Detection in iOS5 works even with Johnny Deep's multiple eyes photo!

Was following this example from ManiacDev.com which as below quickly detects the eyes and mouth in a few seconds time and highlighted all of them.

I then quickly tried it with the Johnny Deep's multiple eyes photos and it sort of works too! Except the left side picked up the wrong one, not bad isn't it?

Problem after upgraded iPad 2 to iOS 5 [fixed]

I have an iPad 2 with wifi only, and I always connect to my iPhone 3GS (iOS 4.3.5) through Bluetooth and then using the "personal hotspot" on iPhone, I can share the Internet connection and do lots of stuffs on the net with the much bigger screen.

However, after I upgraded my iPad 2 to iOS 5 yesterday, the Bluetooth connection still works, but it can't get any Internet connection any more!

This is really annoying. I guess can also upgrade my iPhone to iOS 5 to see if that would fix the problem, but there's first of all the risk that it still won't work, plus I will then loose a device for testing with iOS 4!!

What a pain, any one having similar issue?

[UPDATE] saw quite a few people experiencing similar issue with iPad after upgraded to iOS 5 - but mostly for connection through router, some of them got it fixed after router restarted. So I tried that too - I power off and then restart my iPhone. And guess what, it works! But why a restart is required is still a mystery to me...

Can iOS5 Face Detection API detect this?

Seen quite a few blogs/news articles taking about the new iOS5 Face Detection API "CIFaceFeature" which has properties like "hasLeftEyePosition", "hasRightEyePosition", "hasMouthPosition", ...etc. Would be interested to see how it really works.

Also, just wondering, what would be the result if we run it against Johnny Deep's famous "multiple-eyes" image? :-)

[UPDATE 2011-11-08] Yes it works! See this post about the result when I use this photo to run the face detection example... Quite cool!
