I tested aptoide and everything seems to work in it. Does your wifi icon in sfdroid show an exclamation mark (!)? If so, sfdroid probably started up without a network connection in sailfish. A reboot and reopen of sfdroid when it has a network connection should fix this. Otherwise, I'll need a logcat since I can't recreate. Please recreate, then run "devel-su /system/bin/logcat > sfdroid" and upload the "sfdroid" file somewhere. I'll add the network issue and reboot workaround to the "Known Issues" section for now.
