So I realized that when I leave my touch on sleep mode, it disconnects from wi-fi eventually (to conserve battery, I assume). This is bad for me because I want to be able to get a push notification from AIM via wi-fi whenever someone IM's me. Well I noticed that when my touch is just sitting on my table and in sleep mode (not connected to anything) sometimes I get a push notification randomly, and its from someone who IM'ed me like 30 minutes ago or something. So I'm wondering, does the touch automatically connect to wi-fi periodically to check if any new push notifications are available? If so, is there a way to choose how often it checks? Also, about the 'fetch' feature for the e-mail. If I set my touch to fetch every 15 minutes, it needs to connect to wi-fi every 15 minutes in order to fetch, no? Well when it connects to wi-fi at that time, will push notifications that have been waiting to be pushed come at that time too, since the touch is briefly connected to wi-fi? Or will it just fetch data strictly for e-mail data, and not connect wi-fi to other apps?
