on 4.2.0 4.2.1 device

Hello

I had an application that will run on some 8800. Some of the features have 4.2.0 and 4.2.1 other APIs. I want to use the net.rim.device.api.ui.Trackball class, which is only available on SDK 4.2.1.

Is it safe to install an application built with on 4.2.0 4.2.1 devices?

No, it is not without danger.

It can cause errors of execution, when an internal reference to the JVM in the byte code of your application cannot be resolved.

  • pop up saying that a device is connected to my Imac with IP

    My iMac is completely compromised after having an intrusion on my internet router.

    I supported everthing this summer.  I tried to reset my IMac to factory settings.

    A pop up came in September saying that another device is connected to my internet

    connection with an IP address.  I called my provider of intellectual property, and they said it was a

    Xerox printer.  I don't have a Xerox printer.

    I followed all the steps in trying to get rid of malware and successfully, I think, to get rid of

    Depending on your router model, there should be a way of

    disable DHCP.  It is a method used by the router to assign

    IP addresses on your local network when any device attempts

    connect you to it.  You can then manually assign IP addresses to only

    These devices that you want to have access to your router.

    If you haven't already done so, you must also change the password (and also

    username if the router required) to something else and much stronger.

    If it is always the default, with which it was delivered, anyone can understand this.

    In addition, if the router is a network capable wireless as well, you must disable the comments

    access and create stronger passwords.

    Also, make sure that all firewalls is enabled on devices and the

    router.

    As every router is different, you will need to check the manufacturer's instructions

    to make these changes.

  • Remove device management profile?

    Hello

    My friend has an iphone 6 and it hes a company certificate (Swisscom). 1 minute after activation almost all applications disappear, and you can only make calls and take pictures.

    Is there a way to remove this kind of profiles?

    Nope. It is the purpose of the profile.
    DEP he made sure that the iDevices purchased by the company is recorded in the DEP always apply the strategy of the company via a profile (using an MDM server) when you set up.

    The only way to change the restrictions is to ask administrators to the Swisscom MDM server - they can modify and manage anything remotely. I'm not familiar with Mobileiron (MDM server provider) - perhaps that he may try you on https://mds01.swisscom.ch/login.html with his credentials of the company? But the chances of him being able to manage the device in this way are very thin.

    My condolences to the Swisscom employees if this madness is standard. There is certainly no need to cripple a phone in this way, unless you work for an agency of 3 letters or something.

  • Time capsule: no backup, device not found but internet work

    After my vacation my Time Machine's backups. The Internet works, but the backup utility cannot find the device more. The last backup is a few days before my holiday a month ago.

    In the Time Machine - page select disk (config) TC logo is there, but the only option is to 'remove' the current disk/copy.

    El Capitan, Time Capsule + Airport Express; Time Machine

    I think I have solved the problem in a strange way:

    -J' watched the disc of airport in the Finder; He had to connect to the TC unit (password information automatically), and content (two sparsebundles) was now visible.

    And after that, at the same time the backup started. It will take 7 hours to complete the backup. It seems that it is regarded as an initial backup then.

    Furthermore, the disc name is passed automatically Time Capsule etc. airport to disk .
