Insomnia works fine on my iPhone. Recently got an iPod touch 2.2.1 (5H11a) jailbroken running insomnia it shows as "On" in the little bubble over the insomnia icon but it still seems to drop off wifi when it sleeps. I also installed KeepAwake (much nicer, I'll put that on my iphone to replace insomnia) but that also seems to drop off wifi when the iPod touch sleeps. Am I missing some dependency maybe? Has anyone else seen this?
