Missing a few bugs Apple...

You might want to make it a bit Snappier(tm) as well.
Apple will update iOS 4.3 to 4.3.1 within a week or two, it has been claimed. No prizes for spotting that it'll be a relatively minor release - a fact highlighted by the bug-fix list posted by BGR. The new firmware contains only two notable tweaks: new baseband code for the iPad and iPhone 3GS, and "fixed iPad 2 jailbreak …
I'm not a jailbreak expert but I think the jailbreak equivalent to Hotspot is something called MyWi, which is $24.99 on Cydia, or $4.99 if you're upgrading from an older version. So if you do jailbreak, be prepared to spend some cash. It's not all open source and freebies outside of the walled garden.
To be fair, there seems to be a ridiculous amount of dodgy software repositories for jailbroken phones... I don't condone this.
I am just surprised by the sheer volume! I added one, looking for a specific 'free' based legacy software item, and up came all new cydia software.
I see people will still do anything for a free sandwich.

"I understand that Mr. Jobs et al are withholding the WiFi Hotspot feature from pre-4 iPhones."
4.3 is no longer under NDA since build 4A304a was officially released, so I can rather grumpily inform you that the hotspot feature will work just peachy on your 3GS, but your carrier will almost certainly require you to pay them for a tethering plan just the same as before, so don't get your hopes up.
I've no idea about the other carriers, but O2 in particular will take you to a 'pay up or fuck off' website as soon as you try to activate the feature, offering to sell you a bolt on of 500MB for GBP 7.50 a month (IIRC), which is frankly laughable unless you absolutely must have the convenience of tethering. But then again, what are you going to tether to it ? Netbook ? Get a PAYG dongle. iPad ? Get a 3 PAYG iPad SIM.
I can't advise you to jailbreak your phone or Steve Jobs will send flying monkeys to bukakke me, but that's the only way you're going to get that functionality without a carrier signed provisioning profile.
Maybe because Apple did not want to pay extra to Broadcom for the special firmware that would make the chip in the 3GS support AP mode? As the iPhone 4 uses a more modern chip, plus it's still sold at premium price maybe they didn't mind.
Btw, the MyWi only supports WEP, AFAIK only Personal Hotspot supports WPA encryption.
