Answer, plus another Q (can't see my HD2's wifi hotspot)
I just got this answer from a similar post on PCCGeeks forum:
your windows mobile creates adhoc WiFi, which supported by full blown OS, like windows xp. android does not recognize this type of network. however, iOs devices can see ad hoc.
the only tablet on the market that can see the network created on your hd2 is the iPad
Oh. Darn. That is bad news. Hmmm... what if I changed my HD2 to run Android (I see lots of forum activity that seems to say that is superior and relatively easy to do, am I right?) If I do that, is there an Android app for the HD2 that would create a wifi hotspot that the Viewpad 7 can see? Surely there's a solution for these 2 pieces of hardware. I'd rather not have to get a SIM with cell phone service for the Viewpad 7, because that's a $30+ a month "solution".
