Free hotspot app and Wake-on-Lan ap on Android?

[New Daddy]

Time to consider upgrade from my HTC Touch Pro2, and I'm torn between iPhone and Android.

One of the many criteria for my decision is (a) availability of FREE WiFi hotspot app and (b) availability of (free or not-free) Wake-on-Lan app.
I know for the iPhone, the answer is no for (a) and yes for (b). How about for the android phone? I've recently seen an add from Verizon indicating that with a new Android phone you get Wifi Hospot function, but the ad was not clear on whether you'd have to pay extra fee for that service. (With my TP2, I use "Wi-Fi Router" app to create free Wi-Fi Hospot.)

Thanks in advance.
