no what i meat was to hack it maybe be able reach the flash
because with Itunes is how you jailbreak/unlock the itouch/iphone
No. iTunes is only installing a jailbreaked customfirmware because iTunes can't distinguish an OFW from an CFW.And with iTunes you can restore the Firmware whenever you want to any firmware as long as it's supported from the device. But the PSP installs only the recent firmware and not older firmwares. And Media Go is only downloading the recent firmware and copying it to the PSP, so it has not the same function as iTunes.
If someone would know how Datel did that ActionReplay can run on every Firmware ??because it's a modified Update?? , couldnt someone do the same an release for example an Firmware 6.21 which is actually an CFW ???
