I'm a IPad wantabee waiting for Ipad2. In the mean time I use my ITouch to get my Comcast mail while traveling logging on to Comcast. I get a lot of junk mail on my Itouch. My computer filters out much of the junk mail while the Itouch/IPad? send all mail through. Is there a IPad/Itouch App that will filter out junk mail?
