Sorry I was a bit off in my description of things. Blackberry push is a proprietary technology so any other method is only trying to mimic their push feature. Activesync doesn't actually fetch in small intervals but keeps a connection open between the server and the device in certain intervals to allow the server to tell the device there is a notification, then the device will go out and pull in that message.

In a BB world the server doesn't tell the device it has a message it just gives the message to the device. The BB is passive in the process. The iPhone actually pulls down the email after receiving notification of a message.

In the end the difference is probably only seconds, but the BB method is the only real true push out there, activesync just gets incredibly close to true push.

This is why turning push on with the iPhone reduces battery life and has no impact on a blackberry.


I can only assume mobileme also operates in the same fashion as activesync but I could be wrong.

I suppose this is kind of off topic though so I appologize.

New features such as tethering and Picture/Video Messaging (MMS) will be available to Rogers customers as of June 19th, 2009 when you upgrade to iPhone O.S. 3.0.

Tethering is the use of your phone as a wireless modem to connect to the Internet from your computer. For a limited time, if you subscribe to a data plan which includes at least 1GB of data transmission between June 8, 2009 and December 31, 2009, and if you have a compatible device, you may use tethering as part of the volume of data included in your plan at no additional charge. Tethering cannot be used with data plans of less than 1GB. To upgrade to a 1GB iPhone data plan go to www.rogers.com and sign into your account or call 1-888-ROGERS1

On the subject of tethering with Rogers and the 3.0 OS I found this on the rogers website.
