I would like to add to Long-Dragon's list...Events that happen at the Kunming International Convention and Exhibition Center outside of the auto show are usually not listed.

I went to an excellent SE Asian Trade Fair last year where vendors from Thailand to Afghanistan showed up to sell goodies to the general public. No mention in GoKunming (with previous management/owners).

A very large Puer Tea Trade show occurred in April of this year at the convention center, and again no mention.

1) There is a version of this floating around online. I used it with success to pass the test:

2) This is an online test web page some blogger in Shenzhen made:

3) There is no official rule guide that details the rules of the road,
in English anyways. Didn't exist electronically or in paper when I
asked my examiners in Kunming. So, mostly you figure out the logic of
the rules from the q&a.

4) I took the exam on a computer in English. It was only available
once a week. There are 100 questions, 60 multiple choice and 40 true
and false. I was allowed two attempts. Any score of 90+ means you
pass. The first time I took the test, I just glanced over the
materials and was only able to score around 85. I studied a moderate
amount for the next attempt a week later, and passed with 90 on my
first attempt.

You just need your passport to buy a prepaid China Unicom 3G card.

There are plenty of China Unicom stores. For Kunming, staff capable of speaking a little English might only be found in the larger/largest store.

China Unicom works for the iPad. You have to do your own research if it works with the Tab. Coverage and speeds for Unicom is decent in most urban areas. China Mobile has the absolute best coverage, but their 3G network is non-standard so you have to make sure your Tab supports it.

300 rmb buys you a prepaid sim from Unicom. That's the lowest amount available. I forget the exact amount of data it provides you, but it's a few gigs worth and good for six months.

If you need a good mountain bike for a day or three, then the place debaser suggested is excellent, but at 40rmb a day plus your passport or 1000rmb for deposit. They do have excellent well maintained bikes and are 100% honest. Their English isn't great, but they've rented enough bikes to foreigners, communication isn't a barrier.

However, at 6 weeks stay, I suggest you buy a affordable/cheap bike and sell it at end of your trip, that is if the bike thieves of Kunming have not solved that problem for you.

In the USA, "factory unlocked" 4S means only the GSM portion is unlocked. I'm pretty sure the HK unlocked model is no different.
