With an "unlimited" plan, be sure to read the fine print stating whether you'll be charged excess for going over the download limit which for unlimited is usually 20gig a month and 15 cents per MB over the limit. Or, whether you simply get capped to a slower speed by going over the limit or are in peak times.
If you get 3G wireless (or almost any wireless for that matter), the main problem you'll have will be with latency as opposed to bandwidth speed. Normal web browsing is fine but for online games, latency can have an impact.
