"If you're not familiar with AT&T's billing practices, you might be a bit shocked to receive your first iPhone bill. Justine Ezarik was less-than amused when her 300-page bill was delivered in a box.
AT&T makes sure to take note of every single text message, every data transaction, and every phone call and print each on a separate line. That means that every time you hit that Safari web browser button, you're adding a line to your bill. Every time you receive or send a TXT message, you're adding a line to your bill. It may not sound like much, but for those of us who live and die by our phone, it adds up quickly. A 300-page bill is certainly uncommon, but 50-100 pages is fairly normal for heavy texters and mobile web users. Those of you with an AT&T account -- especially iPhone users -- may want to consider signing up for electronic billing to save a tree or two."
