Must you download a program that is called tk explorer and put all these weird codes into the highlight?
If so can you please give me step by step instructions with download links as well.
Thank U

go to the second post by brittany! (thats me but on the behold forum) and read the entire thing.

the Samsung Behold is almost the same exact as the Samsung Highlight. i would suggest if u have any more questions on the highlight, go to that forum it has way more people.

EDIT: its also much easier than using tk file explorer and u dont even need to use the computer, which reduces the hassle. u can do this anywhere, just as long u bookmarked the 2 websites.

Thanks brittany! those are great links.

After searching some more i found another way to install apps/games as well

Its a little more involved than Brittanys solution but it works.

The games that i have tried i got off the behold forum and another post in the forum that i linked to earlier. Most have worked.
