I made an application that I think you will find very useful.
User Dictionary Manager (UDM) allows you to edit/export/import/delete/clean the user dictionary words on your Android phone.
I think this will come in very handy for everybody who has to type alot of text in mails, SMSes, etc.
With the help of the User Dictionary Manager application you can export your defined words and import them on another phone - for example, sharing with friends and colleagues.
The homepage of the User Dictionary Manager (UDM) is http://udm.adrianvintu.com
