The new jailbreak will require a PC, unlike browser-based hacks of the past, but an untethered jailbreak is expected to replace the current one, soon.
Apple released 4.3.4 last week to close the exploit used to jailbreak 4.3.3 (as seen here).
If you want to jailbreak your new 4.3.4 device, get out the USB cable and use the latest versions of redsn0w and PwnageTool.
For iPad 2 owners, if you update to 4.3.4 and lose your jailbreak, you will not be able to downgrade so the developers behind the jailbreaks warn to stay away from the latest firmware for the time being.
