i have a nexus S and recently updated to JB I keep my data turned off when not using it to save battery. When I have it turned off, I cannot receive picture/data messages, but I can see that I have received them (just cant download them) so I ust turn on data and click download and i receive the message. With the update to JB, having the data turned off prevent me from bein able to download the messages. When I turn the data on, I still cant download it. It just has the "downloading" icon which I cant press any way I can fix this or should I just revert back to ICS?
