I successfully downgraded JB 4.2.1 to JB 3.1.3 on my 3G. However I cannot install any cydia packages nor re-install ones I bought with 4.2.1. (i.e. Mywi)

I get the NOTE: Cannot Locate package

The package mywi4 cannot be found in your current sources. I might recommedn installing more sources.

The issue may also be caused by a number of other factors......users should attempt to remain reasonably up to date on with Apple fimrware releases.


HELP! I really need mywi
