我有下載iPhone3,1_4.0.2_8A400_Restore.ipsw這個來用,但他好像不行,錯誤代碼3194

this error is shown , u may not have the shsh 4.02
or the confirmation time is too long.

try again , or try other computer ,

我覺得過沒幾天你又會在升上4.1的啦....

好久沒關心我的i phone3g了...
到朋友的升級後...桌面背景都可以自行更改....
就衝著這點....
來去升級了..
結果...
關於還是僅限於鎖定時的螢幕背景...
但主畫面還是未能更換呀.....
有人知道為什麼嗎?????????????

唯一升級的目的...卻做白工.....心有不干....

因為3G沒有這個功能啊XDXD
