Hi,

First of all just to let you know i have jailbroken my iPhone 3G FW 2.2.1 (5H11), BB = 02.28.00... and i have yellowsn0w installed perfectly on that.. and iv patched it with that MobileInstallation file via Fugu (mac)... so i can now download any app (ipa file) and place it in iTunes and sync to my iPhone

NOW...

Is it possible to create a custom ipsw FW for the latest beta 3 FW?? OR ANY beta 3 version?? aka jailbreak it?

And also is it possible to get yellowsn0w working on that? or keep my baseband how it is or something?

And is there a newer patch file for that MobileInstallation file? or can i use the same 1 im using to get the apps for free?

Im considering to upgrade it but im worried il loose the luxury of having yellowsn0w / jailbroken apps / and the free apps i can get...

Please let me know if theres a chance of upgrading to any Beta 3 successfully with the jailbreak and/or yellowsn0w etc...

Cheers!
