Frequently Asked Questions

There is a glossary at the bottom of this page of some of the technical terms that we use at this site.

What is Hebrew in Hand?
Hebrew in Hand is an application for displaying Hebrew text on cell phones and other mobile devices. It supports fully pointed Hebrew, including vowels (nekudot) and cantillation marks (te'amim). No Hebrew fonts or other Hebrew support are needed; everything is included. Download Hebrew in Hand directly onto your cell phone, install it, and run it. Then download Hebrew, Yiddish and mixed language (e.g. Hebrew and English) content to read.
Hebrew in Hand is in active development. We appreciate any comments you may have.
What kind of cell phone can run Hebrew in Hand?
The cell phone must run Java 2 Micro Edition (J2ME, JavaME), with MIDP 2.0 and CLDC 1.0 or later. Most new Java-enabled devices meet these requirements. Additionally, the device must be able to connect to the Internet.
Some carriers are generally supportive of the use of independent third-party software (such as Hebrew in Hand) on phones on their network, while other carriers are not.
How can I find out if my cell phone can run Hebrew in Hand?
See the download page on how to do this.
Will it run on my PDA, Blackberry, Palm or Smartphone?
If your device has J2ME, with MIDP 2.0 and CLDC 1.0 or later, and can download using .jad files, then you should be able to use Hebrew in Hand in its current form. For BlackBerry devices, follow this link. Certain devices may not have Java pre-installed, but you may be able to add it from IBM.
What does it cost?
At this time, Hebrew in Hand and accompanying texts are free. However, depending on the terms of your contract with your carrier, you may be charged for the connection time to download Hebrew in Hand and its associated texts.
How do I get Hebrew in Hand on my cell phone?
Read the detailed instructions on our download page.
How does it work?
Hebrew in Hand is a software program developed by ZigZag, Inc., that includes:
  • a Hebrew font designed especially for small displays;
  • a proprietary text layout procedure for positioning Hebrew letters, vowels and cantillation marks;
  • an implementation of the Unicode bidirectional algorithm for ordering mixed right-to-left and left-to-right text; and
  • line wrap logic to fit text to the particular display being used.
After Hebrew in Hand is installed on your cell phone, you can then download additional files containing Hebrew, Yiddish or mixed-language texts. The Hebrew in Hand application stores these downloaded texts and adds the names of downloaded texts to its main menu. You can then use Hebrew in Hand to select and view any of your downloaded texts.
When I start downloading Hebrew in Hand, I see a warning about the application being unsigned (or not trusted). What's this about?
Hebrew in Hand is an unsigned application. This means that Hebrew in Hand is restricted by your mobile device from making any network connections without your explicit permission, and it cannot access other sensitive functions of your device. This is why you see that message during download.
So why is Hebrew in Hand not signed?
To explain this, we first need to explain certificate authorities. A certificate authority is an independent, recognized and trusted entity responsible for ensuring the identity of anyone distributing signed software. In essence, the certificate authority "signs the signature" that a developer uses to sign software. Mobile devices that can connect to the Internet are set up to recognize one or more certificate authorities. But no single certificate authority is recognized by all devices. If a mobile device does not recognize the certificate authority for the signature on a download, it will not install the application.
However, if an application is unsigned, then the mobile device will (with your permission) install the application but grant it very limited rights. In order to make this version of Hebrew in Hand as widely available as possible, we have left it unsigned.
I got an error message when I tried to download Hebrew in Hand, and it didn't install. What should I do?
Sometimes a mobile device needs to be rebooted before a download. If you get an error message during a download, power your device off, then power it on and try again. If that does not work, see the next question.
I installed and ran Hebrew in Hand without any problems, but I get an error message when I try to use "Get Text" to download texts. What should I do?
Some carriers disable or severely limit the ability of third-party software to access the Internet, even if you have a data plan. The work-around for this problem is to download and run a separate installer program for each text you want to use in Hebrew in Hand, using the same steps you used to install and run Hebrew in Hand. Here are the steps:
  1. Use your device's application management system (or browser application) to go to url
  2. Select a link to download the text installer that you want
  3. If a request for permission appears, respond positively
  4. Once the download is complete, respond "yes" to the request to install and run (or launch) the installer
  5. Exit the installer program and start up Hebrew In Hand. You should see your text listed on the main screen.
Once you have confirmed that the files are available in Hebrew in Hand, you can delete the separate installer programs to free up space on your device.

Not all Hebrew in Hand texts are currently available in this format. If a particular text is a priority for you, please write to us and let us know.
