Do we have the same board? Mine says JY-MCU BT_BOARD 1.02. If it is the same board then I do not know how to proceed save for searching online.

I have same board (JY-MCU BT_BOARD V1.02), but here: http://www.ebay.com/itm/150763254858 says that default baud rate is 9600 and I tried with 38400 and 9600 and it works only with 9600.But another problem: when I type AT I get OK, but when I type AT+VERSION (or ATVERSION, like You said before) I get nothing.Maybe You connected State or Key pins on BT board?Thanks!
when I type AT I get OK, but when I type AT+VERSION (or ATVERSION, like You said before) I get nothing.

If this is the same firmware my board has,that will never work - it uses timing to decide when it has gotten a message, and no onecan type fast enough for long messages to satisfy it. Try using cut & paste into yourterminal app.
The serial monitor isn't a very good terminal. It may be sending a CR or LF or both at the end, my JY-MCU doesn't like those either. You need something that sends the last 'N' in version then stops sending :-). (Maybe the serial monitor can be set to no line ending? I forget).
Then I type 'AT' and press send. An 'OK' returns. All fine and dandy, but other than that AT command, no other AT commands like 'AT+VERSION' work. The module is just sitting there, flashing a red light. My iPhone also can't find any Bluetooth device, no 'Linvor' is showing up.Can anyone shine a light on this one?
Unfortunately yes: iOS won't talk simple serial bluetooth (RFCOMM) without you paying Apple a gazillion dollars and going through something like a Navy Seal training certification process :-). Either that or rooting your iPhone so you can install the stuff described at:http://code.google.com/p/btstack/
So i'll need another device like an older phone with BT to check wether or not the BT module is broadcasting it's name and/or make connections?
