Ok cool...i akso have a samsung captivate with the hotspot feature... When i connect the ipad to it, its just a normal wifi icon... I guess the ipad know lt's tethering via a ios devices and not any wifi router...
I'd like to know if its being tethered via Bluetooth or Wifi. I'd assume bluetooth. I don't know how the iPad would know if the wifi hotspot was from an iPhone or not.
Yeah it's integrated across Lion and iOS5+. It's really annoying because the iPad knows it's tethered using a 3G connection, and therefore restricts BBC iPlayer still (oddly 4OD and AppStore restriction disappears).
I think the iPad to iPhone gets the link symbol since they iPhone is sharing GPS info with the iPad in addition to the WIFI goodness. Take a look at maps when linked, it gets much more accurate.
