If you've got an iPad and you want jailbreak on it, my recommendation is to avoid the update to 3.2.2 (if you haven't done it already). My iPad was bricked today by a an app (it was stuck at boot logo), and I decided that because there was no way of recovering the data I had on it, the best option was to update it to the latest firmware, 3.2.2. But it turned out that it was a bad idea....
Everything went fine, iTunes 10 successfully updated it to 3.2.2, but the problems started when I tried to jailbreak it. Even though it seemed that the jailbreak succeeded, I couldn't find on the home screen the icon/shortcut/logo/app/whatever of the jailbreak tool I tried. I tried both limera1n and greenpois0n, on three different computers. One was running Windows XP, one was on Windows 7, and the other was on Mac OS X. However, on none of the them I got the icon of the jailbreak solution I tried. So, I couldn't get Cydia, so the jailbreak was completely useless.
I really don't know where's the problem, some people reported that both solutions worked fine from the first try on their 3.2.2 iPad, others reported that they tried of few times and than they succeeded, and others reported that they got in the same situation as me. I think that I tried about 25 times to jailbreak that iPad. I really got tired of these iDevices. Unjailbroken, the iPad it is just a bigger iPod, even a much cheaper Android-powered device being able to do much more that an iPad can. But if you jailbreak it (it's legal in case you didn't know, read more here), you'll get a big headache with all the bugs and problems jailbreaking brings.
I ended up by restoring the iPad to 3.2.1 (I had SHSH on file for 3.2.1, so it was quite simple), and I did the jailbreak using jailbreakme.com. If you're still on 3.2.1 (or 3.2) and you want jailbreak, make sure you do it before updating the iPad to 3.2.2, because at that time you can save your iPad's SHSH blobs without any problem.Having SHSH saved on 3.2.1/3.2 (or even on 3.2.2 if you get there with a jailbroken iPad) means that you can anytime downgrade/restore to the version you have that SHSH saved.
