hmm, just stay where you are as of right now. what i mean is use ih8sn0w's auto shsh blob grabber. so you can save your 3.1.3 blob, but i dont know if it still works
Well thank you, and will the first question is how many gb is it? If your ipt2g is mb model and you have more than 8gb than i will upgrade to ios4. As you know i jailbroken 8gb model iphone/ipod mb model and after enabling the multitasking and background, it is extremely slow and lags alot but then again its upto you, ive myself updated to ios4 but before updating, have your 3.1.3 shsh blob backup first incase you dont like ios4. Anything else let me know thanks -lkv-
