When your application records to an to an OutputStream, the Player records in a proprietary streaming video format in memory, which can be persisted as an SBV file. This proprietary container format is documented here- http://docs.blackberry.com/en/developers/deliverab

Is there a known problem with the PatternRepositiory [API]?String received returns part of an email address rather than the full address.
The ActiveTextFieldsDemo is a good example of using StringPatternRepository. You can replace the existing pattern in the ActiveTextFieldsDemo with the regular expression (e.g. "^[_a-zA-Z0-9-]+(\\.[_a-zA-Z0-9-]+)*@[_a-zA-Z0-9-]

What SDK version this code applies to? 4.2+, 5.0?
You can use this API to be used in models such as the curve8320?
We spoke about APIs that apply to range of OS versions (4.2 - 6.0) and explicitly called out the versions when applicable. Most of the APIs discussed are available in 5.0, but I recommend looking at the BlackBerry javadocs for the version information.
The 8320 runs on OS version 4.2 or 4.5. Any API marked 4.5 or below will run on the 8320 devices.
How do we set the default notifications? The defaults always seem to be silent?
The default profile notifications are set by the OS based on the type of profile. E.g. Loud sets the ringer to max, silent sets ringer to silent, etc. Applications cannot change the system level notifications, but can have their own notification alert sounds and LED sequences using the Consequence.startNotification method (see NotificationsDemo)
is there anything a super app must do to work well with devices that have content protection enabled?
Content protection has a default behavior to close every app by invoking the Screen.onClose() on the active screen, in order to reduce the amount of plaintext data in flash memory. First, you can ensure that your data is saved to a persistent store in order to protect your content. When a device is locked, you can only read the persisted application data by obtaining a ticket. You should only hold the PersistentStore ticket as long as your application requires decoding and reading PersistentContent data. The user gets notified when the device is fully secured by content protection, when all tickets are released.
How exactly will the barcode scanning work?

Is there Support for LWUIT in Blackberry?
Which Version Of blackberry Supports the LWUIT API ?
LWUIT is a UI framework that runs on top of the existing MIDP framework (which is supported on all BlackBerry devices). However, you will have to ensure that the MIDP APIs required by LWUIT are available on the BlackBerry platform. For advanced UI APIs, II is recommend you refer to the KB article on Rich User Interfaces - http://supportforums.blackberry.com/t5/Java-Develo
Will there be support for reading and writing to the messages folders such as SMS?
I assume you are refering to the SMS Inbox / Outbox folders in the Messages application. The SMS application is the exclusive owner of the SMS folder. Third party apps can programatically send and receive SMS messages using the Connector API, but cannot interact with the messages stored on the device or SIM.

Can i restrict user to upgrade the OS? i.e. user A has OS v5.0, now i want to restrict him/her not to upgrade the later versions over OSv5.0.
Carriers can push handheld OS software upgrades over-the-air for devices 5.0 and up. Blocking of these over-the-air upgrades is possible on BES-enabled devices only, through the use of BES IT policies. Users can also upgrade using blackberry.com/upgrade, which is blocked for all BES-enabled devices.
Can the native HTTPURLConnection object and Browser field use the same cookies when working with same domain? today we have to manually set these cookies on native HTTP connections from BrowserField.
BrowserField 2 API (BrowserField class in the net.rim.device.api.browser.field2 package) manages cookies on its own now (if BrowserFieldConfig.ENABLE_COOKIES is set to true). Developers can access and set the cookies through new 5.0 API class named BrowserFieldCookieManager, using the website URL as the key to get or set cookies. You can share a BrowserField object's cookies with a HttpConnection by using the BrowserFieldCookieManager.addCookieToRequest(url, HttpConnection) and passing in the HTTPConnection object, where you need the cookie header property set.
