Hi, one question. I have a iphone 4 (running 4.2.1) unit which i got it from Singapore Apple Store. It comes unlock.

Can i use GreenPoison to jailbreak? because i read some where someone mention "unlockers stay away from this version" or something.

Will this affect my unlock iphone 4?

Two questions:

I am currently on firmware 3.2.2. If I upgrade to 4.2.1 will I have to say goodbye forever to 3.2.2? Tiny Umbrella will not save blobs.

If I upgrade to 4.2.1 and jailbreak it with Greenpoison, will I be able to restore to it to the pre-jailbroken state?

Thanks.

Answer to your second question - yes you can restore from jailbreak to factory settings. Cannot even till it was jailbroken.
