I think I have moved my Rock account to Cydia via Google per instruction, now Mywi and My3g no longer can be activated, how can I re-download them from Cydia as I don't see my Rock purchases in Cydia.

I have a jailbroke iphone version 3.1.2, both software worked fine until I moved accounts to Cydia and they don't work anymore. I can't enable tethering in Mywi, My3g also has problem working.

I like to redownload my purchased software (purchased from Rock) from Cydia, how can I do that?
