關於JB的幾個問題 - 改機

間單說只要原本就是不鎖 SIM 的 iPhone 都可以升級 baseband
意思就是直接升官方 3.1.2 先更新到最新的 baseband 吧
之後再用 pwnagetool 直接回復成 dev-team 的自製韌體就好

SIM Free/SP Unlocked/Factory Unlocked iPhone 3G(S)
This applies if you bought your iPhone 3G(S) for $$$$$$$.
This model of iPhone 3G(S) doesn’t have an Service Provider lock
(aka factory unlocked) and you are able to put any SIM card into the phone
and get service.
Your phone is already unlocked so you do not need to worry
about baseband updates,
you can use PwnageTool to create an ipsw and then use this to update and
jailbreak your phone.

至於原生 3.0.1 的 iPhone 黑雨後再刷一次 pwnagetool 的自製韌體會比較好
黑雨只是讓原生 3.0.1 一個讓你可以刷自製韌體的管道而已
之後再將 cydia compelete upgrate 一次

個人使用 3.1.2 的感覺記憶體管理跟效能以及電源管理都比 3.0.1 還要好
如果你是 SIM-Free 的 iPhone，升級 baseband 吧
