Hi everyone. I hope this is not a repost but Go Bible and YouVersion are offering free applications of the Bible for your cellphone or portable media player. Go Bible is available in KJV but you can also check for other versions in their forum. Some of the features of Go Bible is that it allows you to search, bookmark, send verses to others as an SMS or MMS. You can also install the whole Bible on your phone or just specific books.

YouVersion offers KJV, NKJV, NIV, ESV, ASV and many other translations of the bible. Some versions are only available in online mode while others are offline.

Here's the links:
