更新韌體2.2

[finebonechina]

韌體2.1已jailbreak的版本想換軔體2.2

換完後須要再重新jailbreak一次嗎?

我重新jailbreak一次後

用ifunbox看裡面的資料夾

很多都重覆出現theme,ringtone等等

這樣是正常嗎??

not sure which iphone you have, if you have iphone 2g, you can just use itune upgrade, but if you do it, you only have apple app, if you need other 3rd party software, you better to use pwn tool or quickpwn to do it, it is not matter JB or not.
