I have the original iPad (1) with ios 3.2 Can I update it to at least 4.2?

Answer 1

You can update to the current version (5.1.1) as that is the only version that is 'signed' by Apple (some people have said that iOS 5 slows down the first gen iPad).
You will need the latest version of iTunes on your computer - you can check if you are up-to-date via, on a PC,  'Help > Check For Updates', and on a Mac 'iTunes > Check For Updates'
When you have that installed, connect the iPad to it and copy any purchases off it via File > Transfer Purchases and then force a backup of the iPad by right-clicking the iPad 'Device' on the left-hand side of iTunes and selecting 'Backup'. You may also want to copy off the iPad any important documents, notes, files etc e.g via the file sharing section at the bottom of the device's apps tab when connected to iTunes, via wifi, email, dropbox etc - they should be included in the backup, but it's best to have a copy of them outside of the backup just in case.
You can then start the update by selecting the iPad on the left-hand side of iTunes, and on the Summary tab on the right-hand side clicking the Check For Updates button.
