You people don't spend much time looking at previous declaration dates. On several occasions the declaration has been later than the 20th of the month. Anyway, the market has already priced in the reduced dividend. The only way there will be a big change in stock price is if the dividend is maintained.
I am a very conservative investor, but I do think it is time to "back up the truck" as they say. . .actually, I wish they would slash the dividend in half, and use the money to build out 4G, etc. This is still a great franchise, and with a sustainable dividend, of say 5%, it should go back to about $8 to 10 with decent cash flow.
