Upgrading iOS firmware on jailbroken iPad

Ipad_smallI’ve been holding off on upgrading the firmware on my iPad since I bought it, as I didn’t want to lose my jailbreak, or end up with a tethered jailbreak.  Although it doesn’t leave the house much, having to connect the device to a PC to reboot it sounds like too much hassle.

With the release of greenpois0n, I finally took the plunge and upgraded from 3.2 to 4.2.1.  It was actually less hassle than I expected, though largely because the iPad doesn’t have the same problems as the iPhone, where upgrading via Apple will also upgrade the baseband, which could possibly break any carrier unlock.

The whole process took a couple of hours, including downloading & installing the latest version of iTunes, upgrading the firmware from within iTunes, jailbreaking using the greenpois0n app, and then re-installing the jailbroken apps (sbsettings, multifl0w, infinidock, winterboard, aquarium hd, fake carrier)

I’m yet to do this on my iPhone, though I’m still contending whether I want to use the official Apple upgrade option and then use greenpois0n to jailbreak it, which will also upgrade the baseband and break the carrier unlock –  though I’m not using this anyway but losing it makes the phone harder to sell in future, or whether to restore a custom 4.2.1 IPSW, but go through all the aggravation of re-installing all of my apps manually.

Either way, it’s nice to finally have 4.2.1 on the iPad.  I’m a big fan of folders and organizing my apps into groups, so that’s the biggest obvious benefit for me.  I’m not using AirPlay (haven’t got an Apple TV), and AirPrint seems useful but only works with selected printers, though there seem to be some apps and hacks to work around that which needs further investigation.
