i see the usb ps jailbreak2 dongle for ps3 here http://www.priceangels.com/USB_PS_Jailbreak2_Dongle_for_PS3_p10475.html for $19.99usa.

and the ps break revolution usb chipset adapter here http://www.priceangels.com/Direct_USB_PS_JailBreak_PS3_Break_Hot_Spot_Upgrade_V1.1__p9132.html

so what is best one to get ??

the usb ps jailbreak2 dongle for ps3?

or the ps break revolution usb chipset adapter??

does the jailbreaker2 support the same amount games as the ps break revolution?
does the jailbreaker2 support loading of a ps3 backups with out a ps3 blue-ray game in the ps3??

 

to be completely honest i have a feeling allot of these feel like they are produced by the same people .... i mean they all make me feel like the same company with diff faces. they all have websites are are really similar they come in the exact same packaging they post updates about the same stuff on same days (the publishers of real jb devices not the clones (clones = fake ps3 break and use break etc etc.)) every one says they work just fine i havent heard too much from people as far as doa or broke after using so go with the one that you feel is the best deal as long as its upgradeable
