My Graduation is this weekend and I'm hoping to receive my first iPhone 4. I have no wifi in my house so I'm always at my friends, but I want wifi in my house for my DS, ps3, etc. The iPhone 4 has two ways of giving off making a wifi hospot. $20 a month with Verizon or paying a single payment of $20 for an app that does the same thing for jailbroken phones. Will the hotspot feature actually allow me to do mobile gaming? I'd like to know before I start wasting money, any specifics would help as well please.
