I have a jailbroken 3gs running 3.1.2(7d11) with modem firmwear 05.11.07 Im having a ton of crashing problems.. I want to upgrade to 3.1.3 and re-jailbreak it using Spirit....can that be done based on what I have...thanks everyone...
Yes it can. If you used a tethered jb before just upgrade to 3.1.3 and use spirit and you're good to go. However if you rely on an unlock, DO NOT UPGRADE since there is no unlock for the 5.12.01 yet
