I had the same problem as Hélianza. The way I got around it was, once I had good cell service, to open one of the caches I had logged on my phone, press the "log" button, choose the "write note" option, type in a single character so the "post" button became active, then pressed the "post" button. Then all 4 of the caches that had "found" smileys for on the phone, showed up on the web.
