While adding the modmyi repo to my Cydia, I made a typo and added Apt.modmyo.com. Usually typos result in error, but this added the source! I saw Cydia communicate with server and download the release files. When I opened it, there was nothing and I realized my mistake. I removed the empty source, but what about the stuff Cydia downloaded from the server? I checked out modmyo.com in my browser and it's just a parked domain with tons of links.

Could my iPhone have been compromised?

Thanks.
