Apparently Motorola Droid smartphones has been hit by a pretty bad bug which will delete all your contained messages, this will happen if you try to set-up an account again.
Many corporate e-mail accounts are the ones that are mainly affected which is pretty serious, according to iEncyclopedia contacts and calendars still remain on the Droid phone. Droid owners report that POP and multiple Exchange accounts are disappearing and they do not know why which means they are put in a position to re-enter them.
Users have not yet found a fix to this problem after trying to sort it out themselves and are urging Verizon Wireless to act upon this problem as soon as possible, if you re-enter e-mail accounts it will work for a couple of weeks apparently then will be wiped clean again.
Verizon now know of this major problem and are looking into it, please do let us know if you are experiencing the above problem and how it is affecting you please.
