I ran into trouble with this too. Search for and download the "mywi" app (not the WITHOUT Rock version, the version with rock included). This will install mywi and connect you to the account.
PS: I'm posting this on my MBP over 3G using MyWi![]()
I assume you mean search within cydia?
No good. When I type in 'mywi' into cydia search it comes up with something called 'mywin7 theme'
