If you’re getting an XML error when you’re using Facebook Connect to post to a users stream using the function:

$facebook->render_prompt_feed_url()

Then ensure the following:

• You don’t have any double quotes in your attachment
• You don’t have any ampersands in your return URL

For some reason the content is being placed in a hidden field on the page on “mobile” devices.  This isn’t escaping the contents of the post, and hence breaks if you have any of the above.

Highly frustrating!  Hope this helps someone.

WSP Online Solutions is looking for iPhone development projects, partnerships and R&D projects both large and small.  If you have a need for either web based or native iPhone application development – or simply have an idea you’d like to see turned into an application, head over to their site and send them an email!

See below:

Not sure what the update is or why it failed… however it seems that others are having the same problem.  I’ll be trawling the web – if anyone finds a solution or reason for the problem, post a comment!

Update: This has now appeared on ars technica and on the Apple Support Forums as well.  We are all still waiting for a fix from apple!

Further Update: This problem seems to have resolved itself (please comment if its still effecting you).  I am no longer receiving this error – however this may just be my location – I’m on Telstra 3G in Australia.

To summarise these:

• $79 a month gets you an iPhone for free
• Include 800MB of data per month.
• Unlimited data usage in the first month applies.
• Prepaid the phone costs $729 for 8GB and $849 for 16GB phone

These are pretty good, however Optus’ coverage doesn’t better that of Telstra’s Next-G network.  More details are available at the Optus iPhone site.

The 3 mobile network is trying to convince apple to let 3 sell the 3G iPhone in Australia.  They have launched a new website, three.com.au/iphone, which is now live and allows you to register your interest in the iPhone on 3.

If you’re a 3 customer (like me) then head there and register your interest and get help get Apple on side!

• Google automatically serves them up in Gzip format (if your browser supports this)
• Caching is done by Google – you only have to load a copy once, and it can be used at many sites!
• The servers are really quick
• The servers are physically “close” to users (utilising the Google network)
• They are minified

This is very exciting development, as I use many of these libraries in my applications – and the speed they load direct impacts all users of the software I develop.

Now, there is Nimbuzz – a Java application that allows you to chat on all these protocols via your mobile for free!

• Skype (Chat and Calls)
• MSN
• GTalk
• Yahoo
• AOL IM
• Jabber

I’ve been using it for the past couple of days, and have found it to be really good! And if you run Windows, you can download a windows client that syncs your contacts with your mobile phone too! Thoroughly recommended.

After doing this however, I was unable to access my Gmail from my mobile phone (using Gmail for mobile).  The old version didn’t support Gmail for hosted domains on Google Apps.  Until now!  Google has released a new version of this tool called Mail By Google which is a Java based application that now supports Google Apps.  So you can now utilise both Google Apps, Gmail and your mobile!

To download ‘Mail By Google’, point your mobile phone’s browser at:
