AT&T's $99 iPhone

A $99 iPhone has made an appearance, but it's not Walmart that's selling it, but AT&T. But there's a catch. Actually, a few ...

So what are the catches?

• It's the 8GB model 
• The handsets are refurbished
• You have to take out a 2-year contract
• This offer is only available to new customers, so no upgrades
• The offer's only good until New Year's Eve

If you want to get your hands on a 16GB refurbished model then that'll cost you $199.
