If you have an iPhone and a 3G data plan, can you use that with the iPad?
If I buy this it will be my first iPad. Need to figure out if I should get the wifi or 4G one. Also will 16gig be enough space if I don't put any music/movies on it and just use it for internet/netflix streaming/iOS games/apps (just a few at a time)? I have a 16gig iPhone4 and I don't even use more than 3-4gigs of it not counting music.
You can pay $20 a month to att (assuming you have att) for tethering or you can jailbreak your iPhone, buy PDAnet and tether all you want at no additional cost.
