iPad 2 and iPhone 4 tethering question

[MrMacMini]

Got my iPad 2 on launch day and love it but just today I noticed 2 rings at the top left hand corner of my screen instead of the normal wifi icon.

I tether the iPad2 off of my iPhone 4 when Im at work and today I noticed the icon after changing the security type from WEP to WPA2 and changed the password (using My Wi on my iPhone4).

Can anyone tell me what the difference is between the 2 icons? Is 1 way better then the other?

The normal WiFi icon means you are connected by WiFi - the 2 rings is to indicate 'tethering'?

Simples no?

Thanks for the clarification, figured it was something like that.

Good idea to go WPA2 over WEP. WEP is crap and your network can be compromised in less than 60 seconds.

As for the rings, yes, that indicates a tethering session as opposed to a standard WiFi connection from the iPhone to an AP.
