WMwifirouter is an absolute must have if you have unlimited vision on your plan.
It turns you mogul into a wifi router. Everyone with wifi can access your moguls internet through sprint. This is great if you own a laptop, psp, itouch etc... Anything with wifi. I use it for my laptop to surf at sprint speed.
If you upgrade your mogul to the test 3.16 ROM, it'll add Rev A. EVDO for blazing speed and upload. 3.16 also adds GPS in which i use TOMTOM 6 on my phone.
