does anyone have a mobileme account and a vodacom iphone? want to test the "internet apn does not support push theory"...
Push is (for the moment at least) APN independent. I can confirm that. I do not use the iphone APN because for some stupid reason data bundles do not work across APNs, and even though I have a 500MB data bundle bolt on, when I use the iPhone APN I am billed per Kb at R2/MB. I have used internet for a good few months now with absolutely no problems. I am pushing from MobileMe, Yahoo, and from Exchange Active Synch.
As a side note, the "find my iphone" service works very well. Was playing with it last night and it found me within a couple of metres. It is pretty worthless though because you need to have Push set to on : if someone nicks your phone, and immediately turns push off, they have access to your data... So in essence its the same as the Exchange 2007 wipe - it first needs to make an active data connection to the servers.
Fiddling with tethering now...
