How can I develop windows phone 7.8 apps? - windows-phone-7.8

I updated WP7.8 Sdk to my computer(win7), but I can't see any change except a WP7.8 emulator, how can I use those new WP7.8 APIs? For example, how to create a Flip Tile with WP7.8 Sdk?

WP8 is the new API. WP7.8 is only a better UI with tiles, WP7.8 still be WP7.5 no new API for this version.

Offline maps support for iOS 6. Is that possible?

I am developing app that has map functionality and i want to support offline maps as well. Is that possible? Also is it possible to show route with openInMapsWithLaunchOptions without network?
You can't do this with any level of predictability or control with MapKit, but you can with both MBXMapKit and the Mapbox iOS SDK. Both have robust offline support built in.

iOS PhoneGap app using WebGL

Which is the WebView of a PhoneGap app, is the Safari mobile or desktop one?
Is it possible to use WebGL in PhoneGap apps? If not which they work around to use them being able to submit the app to the Apple Store and Android Store
Will I be able to submit to Apple Store a PhoneGap app that uses WebGL?
UPDATE:
iOS 8 brought WebGL support on the UIWebView and WKWebView, so if you don't want to support previous versions you can use it without CocoonJS
See more details on ludei's website
OLD:
If you want to create HTML5 apps with WebGL for iOS and android, try CocoonJS
Right now it's the only way to create WebGL apps that run on iOS and android
I just figured out your issues in two points.They are-
phonegap build app links won't open in safari. For More details Please check HERE
Neither the iOS nor Android browsers support WebGL so it is pretty much a non-starter in PhoneGap.
Apple are clearly working towards supporting WebGL in a more general sense, as can be seen in their support for it in iAds.
It’s possible to take advantage of WebGL using standard embedded web views ( using private APIs).
check HERE too fro browser support.
I personally recommend Ejecta for it being open source:

The Android port doesn't seem widely active, but the main ios port seems well maintained, supporting WebGl.
The latest Android versions support webGL directly - if using older Android versions, Crosswalk can also be used along with phonegap to utilize webgl support.

apps with google maps will work in ios6

Apps built with google maps(iOS5), will work perfectly when users update their devices to iOS 6? There are backward compatibility?
Thanks.
Yes, they should work fine. The API hasn't changed.
The new maps look a bit different, but functionally they are the same.
Just noticed one issue: With the new maps you can not display a map of the whole world (think of setRegion). Try yourself to zoom out as much as posible in the maps app.

Will Facebook iOS SDK 3.0 not work on iOS 3.x?

The Facebook iOS SDK 3.0 Beta says "These new features work with iOS 4.0 and later." Does that mean that it won't work on iOS 3.x? Does that mean that if I have an app that supports iOS 3.x, I cannot use Facebook iOS SDK 3.0?
Correct. Facebook iOS SDK 3.0 will not work with iOS 3.x. We felt that the productivity enhancements (e.g. blocks) in iOS 4.x were simply too useful. The SDK is open source, and we plan to maintain the history, which includes the existing code that does work with 3.x. In this way there is still an option for applications that need to continue to support older versions of iOS.
Pretty safe to say yes, you wont be able to use iOS SDK 3.0, or you will no longer be able to support iOS 3.x.
You can also interpret that to mean that you can use it on iOS 3.x, but some of the features may not work at all, in which case there is no point in changing the SDK that you use because you wont be able to take advantage of the new features.
For what it's worth, Apple announced at WWDC 2012 that more than 80% of iOS users are using iOS 5; a further significant percentage is using iOS 4.
I realize you may have specific business needs to use 3.x, but the world is moving quickly away from 3.x (and even 4.x!) and that should factor in to your platform design.
The previous stable (non-3.0) Facebook SDK is still compatible with 3.x devices.

Will Phonegap current version work on BlackBerry OS version 5?

I am new to mobile development and I was wondering if the applications I develop using phonegap will work correctly on Blackberry OS 5 since they don't support it yet. I won't need any fancy features in my app and wanted to use phonegap to develop for Android, IPhone and Blackberry. But of course I am having problems with the different versions of Blackberry OS just like everyone else.
Thanx.
I had a chance to test this once. I have put my Phonegap application on 5.0 and observed how it behaves. Application has launched properly. But i Observed following issues.
HTML5 is supported but localStorage and sessionStorage is not supported.You need to find an alternative.
HTML Page transition is too slow. End used will certainly not accept the performance.
Few jQueryMobile API's don't work.
You cannot be sure that page will be viewed same as you see in 6.0+. Few elements get distorted.
You need to test each and every UI element and see if it is working proper.For example datepicker displays date on right side of the page instead of left
Few PhoneGap API's don't work or they crash.For example API to launch camera crashes.
After observing above issues i felt that even if phonegap is supported in 5.0 it doesn't make big sense.
Yes, but to run on OS version 4.x you have to target the PhoneGap BlackBerry application, while to run on OS version 5 or 6 you need to target BlackBerry Widgets / WebWorks -- the same application may work on both if you use compatible features, but you'll need two different builds, as though they were two different kinds of phone.
Now the support for earlier versions of BlackBerry has been withdrawn from Cordova 3.0 onwards, which in turn supports BlackBerry 10 only. Refer the following link for more details.
PhoneGap - BlackBerry Support
