I put a custom jailbroken firmware ios 4.0 using sn0wbreeze for my 3gs from 3.1.2 and unlocked it using ultrasn0w.

I am having a problem with ibooks, that is books don't show up in the shelf even when synced from itunes. What's the solution for snowbreeze ? Many people have proposed solutions with redsn0w and pwnage, but what should be done with snowbreeze ? any ideas ?

Here are the solutions with redsn0w and pwnage
Fix iBooks After iOS 4 Jailbreak with Redsn0w 0.9.5b5-4 | Redmond Pie

Pwnage Tool Updated to Version 4.01 [Fixes iBooks Issue] | iPod Touch Tricks

Anybody knows solution with sn0wbreeze ?
