updated cydia now pc doesn't recognize my iphone

[clc3251]

iphone 3gs 4.1 jailbroken greenpoison. Updated cydia apps, now my computer, Windows vista, won't recognize my iphone as previously synced. Wants to restore from backup. Any idea what's going on? Won't I lose my jailbreak if I restore from backup? Itunes 9.2.1.5. Thanks

Why not update your iTunes to 10.x instead of restoring your iPhone and losing your jailbreak.
