I thought that there are standard symbols for the TabBar - but I'm having a hard time finding them! So - are there any at all? If so - where can I find them? I'm using Xcode 4.3, I develop for ios 4 and 5
I'm looking for symbols for the keywords: information, warning/alert, configuration, settings, email
Or do I need to get them from a third party source?
Yes, there are. When creating the UITabBarItem, initialise it with initWithTabBarSystemItem:tag: and for the first argument use the UITabBarSystemItem constant for the image you want (see here for a list of all the possible values and corresponding images available). This feature has been around since iOS 2.0 so you'll have no problems with compatibility.

I am trying to use the UIGlassButton on my iPhone 5 running iOS 6.1 final. There are no errors, just that the UIGlassButton doesn't show up. I also tried this and many other yet finished GlassButton proects on GitHub etc., but none of them works.
What am I doing wrong?
This is exactly the reason why you shouldn't use private API's. Because classes like these are for internal use only, they could change or even be removed in between OS updates.
Imagine you would have used this in an application already in the store, it would either crash or just not show the buttons. A good way to treat your users.
UIGlassButton is a private class and should not be used. To create a similar effect build the button yourself or use images.

I recently found this app, called Atoms in Motion, I want to use the same kind of visualisation in a different app, does anyone know how the real-time visualisation would be done, or have any suggestions for a language I could use to do this? The user needs to be able to interact with the app, for example in Atoms in Motion you can swipe your finger to increase the temperature.
Cheers for any help

In a few words,
1) download cocos2d-iphone
2) use chipmunk or box2d (both included in cocos2d-iphone) to simulate mechanics you need.

I am developing an iPhone app and I need it to call a number that starts with *, is there a way to overcome Apple's restrictions (I know they prevent that)?
If Apple has explicitly restricted something then you can't just "overcome" it in the build in SDK. Usually the only way to get around Apple's security protocols is to develop an application strictly for Cydia.

How do I add effect (e.g. lomo) to a photo on iOS?
To make it simple, I wanna try to make an iPhone app which is similar to those photography apps, and I want a tutorial to start with.
As coreImage framework is not present in iphone (atleast upto iOS 4.0), you will have to do image filtering by hand..You have to iterate through each pixel in an image and work on it..This thread discussed about various image filtering effects in iphone and is very useful..These guys say they are successful in porting imageMagick to iOS but I never tried that..Also I asked a question about implementing polaroid filter in iOS, though it didnt get a good answer, the question itself might be helpful..

Today I read abouts this on hacker news https://github.com/udibr/bitcoinApp which is an interesting app, and is a good resource to learn from.
Do you know about some other open source iOS apps from where I can enrich my iOS/objective-c knowledge?
From a game programmer perspective (mine)...
You can check cocos2d engine.
Oolong Engine (for 3D OpenGL ES).
Also, Canabalt went open source.
