[comma] + though + [comma]

New Smartphones are being released on the market every day. It is easy to simply go ahead and buy the latest phone being advertised, only to find that it doesn’t come with all the features that you need. Some come with a great music system, others offer Office editing software, while still others come with GPS navigational systems. The choices are quite overwhelming. With a little bit of patience and research though you can find the right Smartphone to fit your needs.

- ...and research though you can...
- ...and research, though you can...
- ...and research though, you can...
- ...and research, though, you can...
Do you think that all these examples are correct? The example below makes me think that the fourth is correct.

Inevitably, though, something will go wrong.

#1is the best, though I doubt if many people would object strongly to #2

Would no one object to the use of the commas in your first example?

Actually, very few people would worry about any of them. The use of commas is not a topic of great concern to the average native speaker.

People rarely object to forms that are traditionally correct- plenty object to If I was, but If I were is accepted by both people who use it and those who don't. People who punctuate in a more relaxed manner rarely complain about those who go all the way.
