"Best" iPhone unlock for T-Mobile?

[Mr. Curious]

Just got an iPhone for Christmas.
How to unlock it for use on T-Mobile? For example:
- the easiest way
- the cheapest way
- the least risky way
- the most popular way
- the "newest" way
- the way that is least likely to result in a brick the next time firmware is upgraded

Thanks!
Googling results in many answers that are outdated, uncertain or unclear. I hope to find current, tried-and-true methods.
