If I simply set the deployment target to OS 3.0 will Sharekit still work on devices? It seems working fine in emulater but I don't have a OS 3.0 device to test it further.
I can't seem to find this explicitly stated anywhere in ShareKits docs, after downloading ShareKit and opening the project it appears to have it's deployment target set to iOS 3.2.
Although this isn't exactly a "for sure" indicator that ShareKit doesn't work below 3.2, it seems to suggest that you MAY indeed run into compatibility issues on iOS 3.0.
