iOs & iOs Apps (inc iPhone, iPad, iPod, iBrick)

Serious Q
I am on iPhone 4, happy with it and do not feel the need to upgrade the phone.

So taking the money I would have spent upgrading, do I drop £270 on the iPad mini wifi only and have it tethered to the iPhone 4?
Will that be me sorted for the forseable or should I go full sized iPad4 instead?

Why not wait for the ipad mini with 4g? That whole tethering thing seems like a ball ache. Drains battery and you have to faff with two devices. Monthly plan on 3 is only 7.50 anyway
