Iphone 3G Problems with picking up Bluetooth devices

Question

I've been trying to pair up my Iphone 3G with a bluetooth device and it won't recognise it (or anything else for that matter) even though I've switched this capability on.  Am I doing something wrong and I've not used Bluetooth before?

Answer 1

So tonight I successfully updated my iphone 3gs to ios4. Trying to be nice, I was going to update my dad's 3g after he went to sleep so he could wake up to the new update. no good deed goes unpunished.
So I plugged in his phone and it told me there was an update available, so I sat and waited while it downloaded. Once done, it was automatically starting the update. It first said it was backing up the iphone (which took forever). Then, to my surprise, it said it was restoring the iphone software and firmware. I was scared but then it said it was restoring the music and apps, so i figured it was restoring everything it had just taken so long to back up.
I waited and once it was done, the phone was updated with the new features but was back to it's factory settings. It had no contacts, no calendar events, no email was set up, no notes.
However, it did have the latest photos if I am remembering correctly.
So I frantically restored the phone to the latest back up, which I assumed would be from a couple of hours ago, but it turned out to be from January 17, 2010. I didn't sync the phone before starting the update because I didn't while updating my 3gs earlier, and all went well then.
So now the phone has lost anything that was added to it after January 17, 2010. Including the recent pictures that were still on the phone when it was restored to its factory settings earlier.
WHAT HAPPENED? CAN I FIX IT?
if the phone spent so long backing up before the update then why isn't there a back up file for it?
I am very desperate. my dad is a businessman who had a lot of important contacts and events stored in his phone. He wakes in 15 minutes at 5:00 am and I am just awaiting his anger when he finds a chunk of his data missing.
please help me.
