Okay this is a noobish question but I'm wondering which IOS the Rock band instruments use. I heard it's IOS37, but the normal IOS37 doesn't have the trucha signing bug in it. Now over on Scorehero I was reading how customs have finally started to take off on the Wii for Rockband and I'm curious if there's a patch for IOS37 that allows trucha signing. I know Tona added the signing bug to the new IOS51 so I assume it is possible. So I guess my real question is can someone point me in the right direction to a patcher for IOS37? There are so many home-brew apps I haven't tried yet so if it's included in one of those I'll be sure to try them out. Thanks in advance.
