I kept my 3gs on 3.01 as I wanted the option of jailbreaking, if only to be able to use it for tethering. I decided to download the ncca march madness app so i could watch the games. Unfortunately it requires the latest release. So... what do I do? Should I jailbreak (and what are the instructions please?)? Will I then get the latest os and be able to buy the ncca app? many thanks!
