Selling xbox 360 to get iPhone 4?

The cheapest plan on AT&T you can get will cost you around $70 a month. This is with 200mb of internet (you have to have data with an iphone you can get 2gb for $10 more), 450 minutes, and 200 text messages (if you want unlimited text it will be another $15.00 a month). If everyone switched over to ATT unlimited talk is $120 a month for 2 phones every other phone with that is $50 a month, $30 a month for the whole family with unlimited texting, and then every phone that needs data has to add on their charges (either $15-$25).
