My windows vista can't find any Bluetooth devices?

I have been googling for 2 days now after I got my wireless headset with Bluetooth. The headset works fine, as I managed to pair it with my iPhone, but when I searched for it with my computer, it didn't find anything. Not even my iPhone.

I have an HP 6530b computer with Windows Vista.
I've also tried to change the settings so that my computer allows other devices to find it, but when I press "OK", there's a message that says that some changes could not be saved.
This really shouldn't be necessary as my computer should find other devices with no problem. So I really appreciate any related response!

Linksys Wireless Router Issues?

I have a Linksys WTR54G wireless router. I use it for my laptop, iPhone, and gaming console. Everything normally connects fine with no issues.

However, the past few days I've noticed some strange occurrences. Recently when I try to access a page on my phone via the router, sometimes the page won't open or it will take an unusually long amount of time to do so. I have unplugged the router and the modem and replugged them both back in. The connection to the router has been re-established on the phone, but the same issues continue. I also have trouble connecting my PS3 to the online network at times.

I tried to use the wireless router on my laptop and everything is working as it should. There are no speed or connection issues to speak of.So, why is it that I have a hard time connecting through my phone and console but not my laptop? Each of which is connected wirelessly to the same router.

Can someone please explain?

Spilled alcohol in the headphone jack of my iphone 4

Last night some girl dropped abit of her alcohol in the earphone jack of my iphone 4 and when i opened it to see if it was okay there clearly was some water damage in the screen. I was going to get it fixed because it wasn't that bad but last night i put it on the charger when i got home and this morning i tried turning it on and its completely fried like it won't turn on at all.
