if you are a vet then def go for the recent 4.2.1 redsn0w tethered get what you need do the few reboots that are required then enjoy. you will rarely need to reboot unless you obviously get something that requires it and you should be able to guess if it needs a reboot. JUST DONT LET YOUR BATTERY DIE!!
This is a pretty old thread.
As for JBing a 3.2 Pad...it is a no brainer. I might not have liked the pad as well. In fact, I will NOT upgrade my iPad 3.2 until they have an untethered JB to get to 4.2.1 because 1) no real reason and 2) HATE that Apple changed the rotation lock. HATE!!! I use that rotation lock many times a day, personally when I am bymyself, and when I am showing people stuff on my pad. Usually, I keep it locked, but I unlock it to switch it to different orientations a dozen times a day. 3) I use a USB Card reader to transfer images. Infact, I SOLD the SD card slot. I have cameras that use CF, so, it was a logical solution. I bought the CCK got a card reader that worked for both the SD and the CF, and sold the Apple SD card reader. Apple pulled a FAST one and dumbed down the USB port. The port WAS able to hook up a keyboard to it. Not that I ever wanted to, but I had a small Apple Keyboard that was available if I needed to hammer out a lot of text. Not any more...at least not as a unJB 4.2.1.
3.2 with JB allowed for as many icons in my dock. Folders...with as many apps in them as I wanted (at least more than 12). Tap to Unlock (I HATE sliding to unlock...what a PITA!!!!). Quick access to Brightness...and equally importat to turn off Wifi when out in public places where there IS a wifi, but it is closed...causing the iPad to want to connect to it. It was easier to just let 3g kick in.
Virtual Memory and Backgrounder have been KEY reasons to have my iPad JBed.
I have also used the tethering a great deal...but I consider this to be a bit on the shady side of why JB. All of the above should be allowed by Apple. It is our dang device. I came from the Newton era, and Apple allowed us to install whatever we want. If it were for JB, I probably would have been FAR more eager to jump to Android.
There are less reasons to JB a 4.2.1 pad because of things like built in Multitasking, but still some really good reasons still exist. I do want to upgrade my iPad since managing apps with Categories is awkward at best, but there are too many reasons to wait. I just hope they they can eventually do it...JB 4.2.1 that is.
