What Exploit has been found in Firmware 2.5

Just Wanna know what is actually goin on with firmware 2.5 they actually found a way to run brew on 2.5 or a way to downgrade the firmware to 1.5 coz i tink future games will need firmware 2.5 i guess Gran Turismo 4 will need firmware 2.5 to run and 1.5 is gonna be a thing of the past everybody's gonna hafta buy UMD to play games no more ISO's to play with.

Basically, the firmwear on V2.5 isnt too dissimilar to that of v2.0, which means that it should be alot easier to make a downgrader, since it will be pretty much the same as the 2.0 downgrader

they just find a expliot in the photo viewer like 2.0

Is then no way brew is gonna run on 2.5 dats sick i tink that 1.5 is like windows95 and 2.5 is windows xp no way u can play old dos games on winxp we're gonna be sony's slave all da way f'ck sony and its developers.
