Hi, I'm just stating facts below so it's not a biased Maxis bash...For anyone evaluating iPhone plans this is a good resource:

http://arstechnica.com/apple/news/2008/07/...really-need.ars

I've grabbed a table from it....

In the table below (seconds) represents a realistic estimate of what a 'typical' user may use of a service. This of course varies from person to person.



Bottom line is this.

If you get the cheaper Maxis plans, you will be able to do very basic surfing an email.
You will NOT be able to regularly use most of the heavy duty bandwidth stuff which makes the iPhone cool in the 1st place without killing your data usage.

Let me give you an example:

Last.FM - nope
YouTube - nope
Flickr - nope
Google Earth - nope
Downloading podcasts on the fly - nope
Downloading apps on the fly - nope

etc.

Alternative option: Get a NZ phone 8GB RM1,900 no carrier commitment - get yourself an unlimited 3G package then enjoy your iPhone like it was meant to be enjoyed.
