(adsbygoogle = window.adsbygoogle || []).push({}); I want to jailbreak friendly and customizable in terms of software.
Also will i need E3 flasher or any hardware stuff to jaillbreak any of these ps3's?

I like 2501 but you need to be careful with these model cause some u cannot downgrade. To check if you can run this: You must login or register to view this content.

and yeah you need e3 flasher in order to downgrade to 3.55
Afterwards, you can jailbreak by using any CFW to update 3.55
