WAP vs WAP2 vs IMODE

[Black Viper]

The ad locations have a selection for WAP and IMODE, but the default SMF 2.0 RC2 does not make it clear that WAP or IMODE exists... meaning, at the bottom of the forums, only "WAP2" and RSS is listed.
Can a WAP2 ad location be included?
Am I missing something obvious?

I can easily add WAP2 support to that file as well wasn't sure when each of them was used myself. Imode I am not sure exactly what devices use that.

Thanks.
