I recently decided to upgrade to 3.1.2 from 3.0 and decided to install a custom boot/recovery logo. To do this I first reflashed my ipt2g with redsn0w on 3.0 (since it has to be pre-jailbroken) then: 1. Created images to specifications follow guide on youtube. 2. loaded 3.1.4 and selected ipsw, went through options (only change is increase root to 700MB and deselect icy). 2. on the custom logo screen, images were rejected by the GUI (apparently not true PNGs) so I replaced the default custom logos in pwnagetool.app with my custom ones 3. reticked where you enable custom logos (my ones show up instead of the dev teams) 4. created the ipsw 5. rebooted into windows 7 (runs itunes 8.0.2) 6. restored using my pwnage tool ipsw So far they seem to work but am I setting myself up for hassle in the future? I only ask because of the trick I used to enable the custom logos and the semi-support for the 2g in pwnage tool.
