I have had it with the Yahoo app! Today I get a notification go into the yahoo mail app and get a pop up saying their is a mandotory up date. can't use the app without the up date, but the up date is NOT in the market but is a outside sorce. WTF? scared to download it now the app is useless. Somebody please tell me how to fix it or tell me step be step how to get k9 or another mail clinet to work with Yahoo. I need push notications.
