The smartphone plans are metered, meaning a surcharge for exceeding X GB per month. X can be as little as 200MB or as much as 5GB depending on the plan. That sounds like nothing but I do most of my non-work web browsing and email on the iPhone and use well under 1 GB/month. If you watch a lot of YouTube, use your smartphone like a TV via Hulu, or stream Pandora all day, you may have trouble. You said you used "2 gb" today, that suggests you might have an issue. Ask around for others' experiences (maybe someone will chime in here).
