Seeedstudio sell a neat serial/bluetooth module for a reasonable price.

Have you looked at the one Microchip are advertising? For your use you could probably use the software stack they are supplying for free.

Bluetooth makes a USB HID stack look simple.
Inherently there is nothing simple, ever about BT implementation. Unless you get a module with serial port and its own CPU & stack internally. Then it appears as BT device with com port service on PC.

I've had pretty good luck with the Roving Networks modules. They make both
a low power (RN-42) and a high power version (RN-41). Spark fun makes this
on a breakout board, but it's kind of pricey at $60. However, the modules
themselves are only around $20 (depending on which one you buy) and you can
get them from Mouser. The higher power one really appealed to me.

I ordered Rayban sunglasses from what supposedly was a Seattle address on January 17,2011, tracking shows they are still in China registered mail. The Seattle address later was found to be the main Seattle Newspaper, and not any other organization. :( If I get them at all, I expect them to be counterfeit. I have 1 more week before claiming fraud on the mastercard. I have since bought the glasses locally at a good discount. :)

Longer than normal. Chinese New Year began February 3, so everybody has
a backlog of work and orders, even the ones that went back to work
today. Not to mention the ones that are still home for another week.
What is your dollar reference? I only see one for $21.50

I purchased a few of these some months ago and they work decently. I've got 30 ft through 2 walls easily (cheapo American drywall though). Approx $10, but the store is closed for a while. They also have a version with a breakout board and 5V reg for $14. http://www.mdfly.com/index.php?main_page=product_info&products_id=428

I'm pretty sure they're legit.
Looks like a clone of Deal Extreme. I've bought from Deal Extreme many many
times and they've never disappointed me. Long shipping time is the only
downside, but it's free so can't complain

I was looking at the Goodluckbuy after reading some other replies. But they are expensive on some other stuff, so I'll have a search. I want a custom keypad/trackball for a Media Centre remote and I might use a very small PS/2 keyboard and PS/2 trackball repackaged on a PIC with Bluetooth. (I have the sample 16F/18F code to read PS/2 mouse/keyboard and some PIC 16F877a I'll not be using
the iPhone part of this I really wonder about. Does apple let you get to their bluetooth from a custom application? Everyone I ask (who has done iphone apps) is Not Really Sure. It doesn't seem common, at the least. Let us know how this works out if you go that direction.

To use unapproved stuff the iPhone has to be jailbroken

Bluetooth can be quite complicated. The iPhone does support 'full'
Bluetooth, however they do not implement all the Bluetooth profiles
that make use of the core stack.
Bluetooth is a bit like USB in that you have core specification and
then Classes that sit on top. You would never say a device does not
have Full USB support just because it by default not support all the
classes.
Every Bluetooth profile takes effort to implement, test, then IOP
test, never mind certification / qualification. So phone manufacturers
only support the profiles that best fit there customer use cases, and
for phones that is Hands Free Profile (Mono headsets for calls),
Advanced Audio Distribution Profile (Stereo Music headsets) and Object
Exchange OBEX, (File transfer / vcard, based on the IRDA spec) as core
profiles. Other profiles such as BIP , VDP. SPP.
Sorry Bluetooth is acronym tastic, I'll leave google / Wikipedia for
the ones I haven't decrypted.
The modules that you refer to tend to be based on CSR's BlueCore4
which is a small XAP based processor with a Bluetooth radio sat with
8Mbit Flash. On the Module the Flash has Bluecore firmware and a
custom application that is usually written by the module manufacturer.
You can write your own application, but you will need an SDK from CSR
which I think is out of the price range of hobbiest. The SDK has
example applications for HID mice, headsets, SPP and other profiles.
The module guys take this and put a serial protocol on the top so you
can access this off chip from a small uC. However depending on the
application / volumes you may be able to write it all on the Bluecore
saving the cost of the uC (but adding the cost of the BlueLab SDK :-(
)
Getting back on topic, ... most custom applications use Serial Port
Profile, which as the same suggests is a straight serial cable
replacement. this is good because you have a HW UART one side of the
link and on the other a Virtual comm port for your application. and
the Bluetooth link is transparent once established.
Nokias used to have SPP as it was a simple replacement for the serial
connector on the bottom of the phone for Sync'ing but almost all
phones do not have SPP.. as why would they want to expose a serial
port on a phone?
However all is not lost as phones can expose lower level bluetooth
interfaces, which is why you see Android / iPhone / Symbian
applications that implement extra bluetooth profiles such as SPP.
Unfortunately you sometimes need extra access on the phone... such as
iPhone / jailbroken or Android root.... it just depends...
