Minimum GPRS transaction for billing (plus Winamp remote)

[Guest fraser]

Is there a mimimum size GPRS transaction used for billing? (I'm UK Orange)

I'm implementing a remote control tool for Winamp that will allow you to control winamp and the it's playlist, as well as add files from a library. I'm doing this in XML/XSL and a some javascript, so it will run in Internet Explorer and the only GPRS traffic will be minimalist XML traffic to and from Winamp. All of the images, HTML and XSL files will reside on the phone. This should make it pretty fast and very cheap to use.

For instance, if you were to fire up the app and check the current track and maybe execute a few play control actions, the amount of data transfered would be less than a kilobyte, i.e a fraction of a penny given a £3 per Megabyte tarrif.

Do the mobile operators have a minimum "chunk" they use when adding up all of the GPRS you use. Or is it added up byte-for-byte?

Also, if anyone is able to lend a hand, perhaps with the graphics or HTML layouts, that could be useful. It will be a fully skinnable & programable interface by the way.

Charged by the kilo byte and rounded up to the nearest penny? Think that is O, might be O2.

Charged by the byte I believe! :lol:

Your plugin sounds promising! Keep us posted :lol:

Here's a small proof-of-concept, using a client-side XSL transform that works in Pocket Internet Explorer.

I'm a while away from getting anything public though, got the control stuff working, but I need to wait on the Winamp plugin folks behind BrowseAMP to implement the same tricks they do with *.html files, but on *.xml files.

If anyone has some working javascript code to read the contents of a URL into a string, then I can work around it for now. Any takers? :lol: This page describes a technique for it, but I couldn't get it to work properly when trying to get the value into a variable instead of a obj.innerHTML manipulation.

Did you get any further on this fraser??

It would be cool to control winamp!
