Just a quick heads-up: TinyUmbrella is now updated to support 4.3.2 / 4.2.7 iOS versions. To save your SHSH via APPLE instead of CYDIA (the default) go into Advanced options and UNCHECK the box that clearly says: “Request SHSH From Cydia” then click ‘Apply Changes’ then select your device then click ‘Save SHSH’.
NOTE: it looks like Cydia is giving up the ghost and having some major issues. Notcom re-uploaded TinyUmbrella 4.30.05 for those of you that want to save 4.3.1 via APPLE. Hurry up and do so before 4.3.1 is no longer signed.
