Q: Bluetooth on iPhone 4s won't pair with ipad2

The iphone isn't designed to pair with an iPad; just accessories like headseats, wireless keyboards, headphones and car kits. 

You're welcome.  But Apple gets no revenue from the carrier and has no incentive to design their products to use more of their services.  This is strictly a carrier decision to not provide free hotspots.  I have my suspicious about why Apple doesn't design their phone to pair with other iOS devices, but speculation is against the Terms of Use for these forums.

The internet is full of places where people speculate and share rumors about Apple products.  If you use Google you won't have any trouble find some.

True, Android phones have the Bluetooth modem capability.

However, they still require a tethering plan as does the iPhone

and require to be hacked to use it without a plan. 

if you are trying to use your iphone's cellular connection on your ipad through tethering you can setup a personal hotspot with you iphone and connect you ipad to that, but again like others have said before me you must have a tethering option enabled by your carrier for the option to even show up in the settings.

Not to be late to the party, but I'm having the same issue for different reasons making Randers initial reply even more hard to understand (and somewhat infuriates me with Apple).

Apple advertises that Keynote Remote can control one's presentation on the iPad with your iPhone by either Wifi OR Bluetooth.

How can they advertise that if they aren't designed to pair to begin with?

Instructions for doing exactly that are here: http://support.apple.com/kb/HT3325

It is true that you cannot pair iOS devices via Bluetooth for just any old Bluetooth connection. However, for specific uses (such as tethering, or the Remote app) it is possible.

After reading the instruction for the Bluetooth connect b/w the iPhone and iPad, do I have to download keynote first? I'm asking because without it, following those instructions, the devices will not pair.

You can't follow those instructions without both Keynote on the iPad and Keynote Remote on the iPhone. Steps 3 and 4 require both apps to be opened. Pairing is done from within the app, and the two apps talk to each other.

OK, that's what I was asking and how it appeared. Just wanted to make sure. Thanks
