I signed up for the “iTalk”:http://www.italk.co.nz (internet telephone) service with “Slingshot”:http://www.slingshot.co.nz about a month ago. Here are my impressions after a month of using the service.

h3. Signup and Setup

This is probably the worst part of the “iTalk”:http://www.iTalk.co.nz experience. If you can get over this hurdle, then it’s pretty much plain sailing. The problems I experienced were:

* Unsupported hardware – I was using a Netgear VOIP box, and iTalk only support their own hardware. The forums are a good resource, but it’s pretty much a DIY approach. If you’re non-technical and you don’t have any technical friends, then I’d suggest only using supported hardware.
* Username and password issues – these are generated and then displayed on the setup webpages. They don’t email them to you automatically. Fortunately I have the foresight to have the webpage as a PDF and email it to my gmail account for permanent storage. otherwise you’ll need to call their support people of assistance.
* Customer support – you have to wait on hold forever, and the machine keeps telling you they value you call – yeah right. When you finally get through, they’re nice people and seem to know what they’re doing.

h3. Reliability

When we first started using the service, we had a few issues with calls not coming through. But those problems only lasted a few days and everything came right.

A month down the track, and the reliability seems great. Better than a mobile phone, but not quite as good as Telecom.

I’m using a answer machine at home, but I have heard their voicemail is unreliable.

h3. Call Quality

Fine. You get the odd echo every now and again, but it’s hardly noticeable. We used the service for two weeks before we told anyone we were using an Internet phone – no one had noticed.

Also, you get free caller ID.

h3. The Bill

What can I say – it’s great value. At $10 a month plus 5c a minute calling 24×7 it’s awesome. Mobile calls for 30c a minute – that’s less than half of what I was paying Telecom.

And… the format of the bill is incredible. They:

* itemise all calls, even local ones.
* give you the name of the person you called – WOW!
* date, time etc
* city called

and it’s all categorised into local, national, international and mobile sections. Great work Slingshot!

h3. The Outcome

I’m going to call up Telecom tomorrow to say bye bye. The cable will be snipped. I’ve waited a long time to do this. No longer will we be paying the $40 tax each month.

h3. My Advice

If you interested in this kind of thing, I’d suggest following this process:

# Sign up with iTalk but just get the softphone option
# Get that going first
# Try it out – if you’re happy with it, then buy a “VOIP adapter”:http://www.dse.co.nz/cgi-bin/dse.storefront/en/product/XH9440 for your regular phone
# Call Telecom and ask for their Call Diversion service
# Divert your Telecom number to your new iTalk phone number
# Start using your iTalk phone only. Unplug your Telecom phone
# Don’t tell anyone about this for two weeks or so, and see if anyone notices
# After the two week period, start telling people
# When you get your first bill from Slingshot, start telling all your friends about your new number
# Give it a week or so, and the give the Telecom number the chop

Do you want to try out the new beta version of Firefox 2.0, but none of your extensions are compatible? This brief howto guide will explain how to manually update those important extensions to run in Firefox 2.0.

*About*

Most of the extensions you use will probably work just fine in Firefox 2.0. I have updated many of the extensions I use, and have not had any problems so far. My guess is that there are few, if any changes to the APIs that most Firefox extensions use.

*Step 1: get the XPI file*

Download the XPI file from the mozilla website, or the extension developers website. Save this to a temporary file on your hard drive.

*Step 2: open the file with WinZip*

The XPI file format is a simple Zip archive. You can open it with WinZip or any other compatible Zip archive viewer. You should see something like the screenshot below:

!/images/12.jpg (screenshot of XPI file contents)!

*Step 3: extract the install.rdf file*

The file called install.rdf describes the contents of the XPI file. Extract this file into a temporary directory on your hard drive. With WinZip, you should be able to drag’n'drop the file onto your desktop.

*Step 4: edit the install.rdf file*

Use notepad, or a similar text editor to open the install.rdf file. It contains a number of XML tags. You should look for an entry named em:targetApplication – this defines which applications and versions the extension will operate with. It should look similar to the screenshot below:

!/images/11.jpg (screenshot of install.rdf file)!

You will need to change the maxVersion setting to match the version of Firefox that you are using. In the example above, I have set the maxVersion to 2.0+

Note: there may be other instances of the targetApplication tag – these may declare that the extension can operate with other Mozilla based applications – for example the Flock browser. You can safely ignore those applications that you are not interested in.

*Step 5: update the XPI file*

Open up WinZip a second time, and add the updated install.rdf file back into the XFI archive. Using drop’n'drop may be the simplist way to achieve this. Confirm that the file has been updated by checking the date field of the install.rdf file. It should be today.

*Step 6: install the XPI file*

Install the XPI file by dragging and dropping it into Firefox. The Software Installation dialog will appear. Press the Install button to proceed. You will be prompted to restart Firefox.

*Step 7: confirm the installation*

After you have restarted Firefox, you can check that your extension has been installed by selecting the Add-ons option from the Tools menu. You should see your extension listed.

*When it all goes bad – uninstall*

The extension you have manually upgraded may not work correctly in Firefox 2.0. This may be due to some upgrade issues that can only be solved by the extension author. You’ll just have to be patient and wait until a new release supports the new Firefox.

To uninstall your faulty extension, you can remove it from the Add-ons panel. If this fails, you may need to start Firefox in safe mode. Select Start > Programs > Mozilla Firefox > Mozilla Firefox (Safe Mode). Then remove the extension from the Tools > Addons menu.
